Part Number：TPS92512HVDGQT
Manufacturer：Texas Instruments
Category ： Integrated Circuits PMIC - LED Drivers
Description ：IC LED DRVR RGLTR PWM 10HVSSOP
Detailed Description：LED Driver IC 1 Output DC DC Regulator Step-Down (Buck) PWM Dimming 2.5A (Switch) 10-HVSSOP
Type：DC DC Regulator
Topology：Step-Down (Buck)
Applications：Street Lighting / Emergency/Exit Lighting / General Industrial and Commercial Illumination / Retail Lighting / Appliance Lighting / Transportation Lighting / Channel Letters / Light Bars.
Features：Integrated 200-mΩ High-Side MOSFET / 4.5-V to 42-V Input Voltage Range (4.5 V to 60 V for the TPS92512HV) / 0 V to 300 mV Adjustable Voltage Reference / ±5% LED Current Accuracy / 100-kHz to 2-MHz Switching Frequency Range / Dedicated PWM Dimming Input /Adjustable Undervoltage-Lock-Out / Overcurrent Protection / Overtemperature Protection / MSOP-10 Package with PowerPAD™ .
The TPS92512/HV are 2.5A step-down (buck) current regulators with an integrated MOSFET to drive high current LEDs. Available with 42 V and 60 V (HV) input ranges, these LED drivers operate at a user selected fixed-frequency with peak-current mode control and deliver excellent line and load regulation.
The TPS92512/HV LED drivers feature separate inputs for analog and pulse width modulation (PWM) dimming for no compromise brightness control achieving contrast ratios of greater than 10:1 and greater than 100:1, respectively. The PWM input is compatible with low-voltage logic standards for easy interface to a broad range of microcontrollers. The analog LED current setpoint is adjustable from 0 V to 300 mV using the IADJ input with an external 0 V to 1.8 V signal.
For multi-string applications using two or more TPS92512/HV LED drivers, the internal oscillator can be overdriven by an external clock ensuring all of the converters operate at a common frequency thereby reducing the potential for beat frequencies and simplifying system EMI filtering. An adjustable input under-voltage lockout (UVLO) with hysteresis provides flexibility in setting start/stop voltages based upon supply voltage conditions.
The TPS92512 includes cycle-by-cycle overcurrent protection and thermal shutdown protection. It is available in a 10-pin HVSSOP PowerPAD™ package.
Part Number：TPS71530DCKR
Manufacturer：Texas Instruments
Category ：Integrated Circuits PMIC - Voltage Regulators - Linear
Description ：IC REG LINEAR 3V 50MA SC70-5
Detailed Description：Linear Voltage Regulator IC Positive Fixed 1 Output 50mA SC-70-5
Applications：Ultralow Power Microcontrollers / Cellular and Cordless Handsets / Portable and Battery-Powered Equipment.
The TPS715 low-dropout (LDO) voltage regulators offer the benefits of high input voltage, low-dropout voltage, low-power operation, and miniaturized packaging. The devices, which operate over an input range of 2.5 V to 24 V, are stable with any capacitor greater than or equal to 0.47 μF. The low dropout voltage and low quiescent current allow operation at extremely low power levels. Therefore, the devices are ideal for powering battery management ICs.
Specifically, because the devices are enabled as soon as the applied voltage reaches the minimum input voltage, the output is quickly available to power continuously operating battery charging ICs.
The usual PNP pass transistor has been replaced by a PMOS pass element. Because the PMOS pass element behaves as a low-value resistor, the low dropout voltage, typically 415 mV at 50 mA of load current, is directly proportional to the load current.
The low quiescent current (3.2 µA typically) is stable over the entire range of output load current (0 mA to 50 mA).

Detailed Description：35V Off-State 400 A Ipp TVS Thyristor DO-214AA, SMB
Applications：Any sensitive equipment requiring protection against lightning strikes and AC power faults. These devices are dedicated to central office protection as they comply with the most stressful standards. Their low capacitances make them suitable for xDSL.
Features：Bidirectional crowbar protection / Voltage range from 8 V to 400 V / Low capacitance from 20 pF to 45 pF @ 2 V / Low leakage current: IR = 2 µA max / Holding current: IH = 150 mA min. / Repetitive peak pulse current:IPP = 100 A (10/1000 µs）.
The SMP100LC is a series of low capacitance transient surge arrestors designed for the protection of high data rate communication equipment. The low capacitance of the devices avoids any distortion of the signal and is compatible with digital transmission line cards (xDSL, ISDN...).
SMP100LC series tested and confirmed compatible with Cooper Bussmann Telecom Circuit Protector TCP 1.25A.
The SMP100LC-xxx with the fuse TCP1.25A or TCP2A is compliant with Telcordia GR1089 (lightning and AC power fault tests),ITU-T K20/K21 (lightning and AC power fault tests), TIA/EIA-IS-968 (formerly FCC Part 68 lightning tests), and UL60950 (AC power fault tests). The use of the TCP1.25A allows the SMP100LC-xxx to be safe for the 2nd level (Briteria) AC power fault tests.
