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.
Part Number：ULN2803ADWR
Manufacturer：Texas Instruments
Description：TRANS 8NPN DARL 50V 0.5A 18SO
Detailed Description：TRANS 8NPN DARL 50V 0.5A 18SO
Category：Discrete Semiconductor Products Transistors - Bipolar (BJT) - Arrays
Applications：Relay Drivers，Hammer Drivers，Lamp Drivers，Display Drivers(LED and Gas Discharge)，Line Drivers，Logic Buffers，Stepper Motors，IP Camera，HVAC Valve and LED Dot Matrix.
The ULN2803A device is a 50 V, 500 mA Darlington transistor array. The device consists of eight NPN Darlington pairs that feature high-voltage outputs with
common-cathode clamp diodes for switching inductive loads. The
collector-current rating of each Darlington pair is 500 mA. The Darlington pairs may be connected in parallel for higher current capability. Applications include relay drivers, hammer drivers,lamp drivers, display drivers (LED and gas
discharge), line drivers, and logic buffers. The ULN2803A device has a 2.7-kΩ series base resistor for each Darlington pair for operation directly with TTL or 5-V CMOS devices.

A standard series of inductors (both through-hole and surface-mount types) are available from several different
manufacturers optimized for use with the LM2594xx series. This feature greatly simplifies the design of switchmode power supplies.
Other features include an ensured ±4% tolerance on output voltage under all conditions of input voltage and
output load conditions, and ±15% on the oscillator frequency. External shutdown is included, featuring typically
85-μA standby current. Self-protection features include a two stage frequency reducing current limit for the output
switch and an overtemperature shutdown for complete protection under fault conditions.
The LM2594HV is for applications requiring an input voltage up to 60 V.
