Order Information ：
Part Number：TPS2553DDBVR
Manufacturer：Texas Instruments
Category ：Integrated Circuits Power Management (PMIC) Power Distribution Switches, Load Drivers
Description ：Power Switch/Driver 1:1 N-Channel 1.5A SOT-23-6
Features：Slew Rate Controlled, Status Flag
Fault Protection：Current Limiting (Adjustable), Over Temperature, UVLO
Applications：USB Ports/Hubs / Digital TV / Set-Top Boxes / VOIP Phones
The TPS2552D and TPS2553D power-distribution switches are intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered and provide up to 1.5 A of continuous load current.
These devices offer a programmable current-limit threshold between 75 mA and 1.7 A (typ) via an external resistor. Current-limit accuracy as tight as ±6% can be achieved at the higher current-limit settings. The power-switch rise and fall times are controlled to minimize current surges during turn on/off.
The TPS2552D/3D devices limit the output current to a safe level by using a constant-current mode when the output load exceeds the current-limit threshold.
An internal reverse-voltage comparator disables the power-switch when the output voltage is driven higher than the input to protect devices on the input side of the switch. The FAULT output asserts low during overcurrent and reverse-voltage conditions.
Part Number：LM2596SX-5.0/NOPB
Manufacturer：Texas Instruments
Category ：Integrated Circuit Power Management (PMIC) Voltage Regulators - DC DC Switching Regulators
Description ：Buck Switching Regulator IC Positive Fixed 5V 1 Output 3A TO-263-6, D²Pak (5 Leads + Tab), TO-263BA
Applications：Appliances / Grid infrastructure / EPOS / Home theater
The LM2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version.
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixedfrequency oscillator.
The LM2596 series operates at a switching frequency of 150 kHz, thus allowing smaller sized filter components than what would be required with lower frequency switching regulators. Available in a standard 5-pin TO-220 package with several different lead bend options, and a 5-pin TO-263 surface mount package.
The new product, LMR33630, offers reduced BOM cost, higher efficiency, and an 85% reduction in solution size among many other features. Start WEBENCH Design with the LMR33630.
Part Number：IL3522E
Manufacturer：NVE Corp/Isolation Products
Category ：Digital Isolators
Description ：RS422, RS485 Digital Isolator 2500Vrms 3 Channel 40Mbps 30kV/µs CMTI 16-SOIC (0.295", 7.50mm Width)
Applications：Factory automation / Industrial control networks / Building environmental controls / Equipment covered under IEC 61010-1 Edition 3 / 5 kVRMS rated IEC 60601-1 medical applications
The IL3522 is a galvanically isolated, high-speed differential bus transceiver, designed for bidirectional data communication on balanced transmission lines. The device uses NVE’s patented* spintronic Giant Magnetoresistance (GMR) technology.
A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life.
The IL3522 delivers an exceptional 2.3 V differential output into a 54 Ω load over the supply range of 4.5 V to 5.5 V. This provides better data integrity over longer cable lengths, even at data rates as high as 40 Mbps. The device is also compatible with 3 V supplies, allowing interface to standard microcontrollers without additional level shifting.
Current limiting and thermal shutdown features protect against output short circuits and bus contention that may cause excessive power dissipation. Receiver inputs feature a “fail-safe if open” design, ensuring a logic high R-output if A/B are floating.
Part Number：A3P400-FGG144
Manufacturer：Microchip Technology
Category ：Integrated Circuit Embedded FPGAs (Field Programmable Gate Array)
Description ：ProASIC3 Field Programmable Gate Array (FPGA) IC 97 55296 144-LBGA
ProASIC3, the third-generation family of Microsemi flash FPGAs, offers performance, density, and features beyond those of the ProASICPLUS® family. Nonvolatile flash technology gives ProASIC3 devices the advantage of being a secure, low power, single-chip solution that is Instant On. ProASIC3 is
reprogrammable and offers time-to-market benefits at an ASIC-level unit cost. These features enable designers to create high-density systems using existing ASIC or FPGA design flows and tools.
ProASIC3 devices offer 1 kbit of on-chip, reprogrammable, nonvolatile FlashROM storage as well as clock conditioning circuitry based on an integrated phase-locked loop (PLL). The A3P015 and A3P030 devices have no PLL or RAM support. ProASIC3 devices have up to 1 million system gates, supported with up to 144 kbits of true dual-port SRAM and up to 300 user I/Os.
ProASIC3 devices support the ARM Cortex-M1 processor. The ARM-enabled devices have Microsemi ordering numbers that begin with M1A3P (Cortex-M1) and do not support AES decryption.

Part Number：LM3886TF
Manufacturer：Texas Instruments
Category ：Integrated Circuit Linear Amplifiers Audio Amplifiers
Description ：Amplifier IC 1-Channel (Mono) Class AB TO-220-11 Isolated
Applications：Component stereo / Compact stereo / Self-powered speakers / Surround-sound amplifiers / High-end stereo TV
The LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4Ω load and 38W into 8Ω with 0.1% THD+N from 20Hz–20kHz.
The performance of the LM3886, utilizing its Self Peak Instantaneous Temperature (°Ke) (SPiKe) protection circuitry, puts it in a class above discrete and hybrid amplifiers by providing an inherently,dynamically protected Safe Operating Area (SOA).
SPiKe protection means that these parts are completely safeguarded at the output against overvoltage, undervoltage, overloads, including shorts to the supplies, thermal runaway, and instantaneous temperature peaks.
The LM3886 maintains an excellent signal-to-noise ratio of greater than 92dB with a typical low noise floor of 2.0µV. It exhibits extremely low THD+N values of 0.03% at the rated output into the rated load over the audio spectrum, and provides excellent linearity with an IMD (SMPTE) typical rating of 0.004%.
Part Number：UC3854BN
Manufacturer：Texas Instruments
Category ：Integrated Circuit Power Management (PMIC) PFC (Power Factor Correction)
Description ：PFC IC Average Current 200kHz 16-PDIP
The UC3854A/B products are pin compatible enhanced versions of the UC3854. Like the UC3854,these products provide all of the functions necessary for active power factor corrected preregulators. The controller achieves near unity power factor by shaping the ac input line current waveform to correspond to the ac input line voltage. To do this the UC3854A/B uses average current mode control.
Average current mode control maintains stable, low distortion sinusoidal line current without the need for slope compensation, unlike peak current mode control.
A 1%, 7.5-V reference, fixed frequency oscillator,PWM, voltage amplifierwith soft-start, line voltage feedforward (VRMS squarer), input supply voltage clamp, and over current comparator round out the lilst of feataures.
Available in the 16-pin N (PDIP), DW (SOIC Wide),and J (CDIP) and 20-pin Q (PLCC) package. See Ordering Information table for availability by temperature range.
