LM2597HV - SIMPLE SWITCHER Power Converter  Step-Down Voltage Regulator

I like circuit power supply, See to more website. This is IC LM2597HV (Good IC Step-Down Voltage Regulator)

Intro detail:

The LM2597/LM2597HV series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 0.5A load with excellent line and load regulation.

3.3V, 5V, 12V, and adjustable output versionsAdjustable version output voltage range, 1.2V to 37V (57V for HV version)?┬▒4% max over line and load conditionsGuaranteed 0.5A output currentAvailable in 8-pin surface mount and DIP-8 packageInput voltage range up to 60V150 kHz fixed frequency internal oscillatorShutdown# /Soft-startOut of regulation error flagError output delayBias Supply Pin (VBS) for internal circuitry improves efficiency at high input voltagesLow power standby mode, IQ typically 85 ?╬╝AHigh EfficiencyUses readily available standard inductorsThermal shutdown and current limit protection
