LM2594HV Datasheet (National Semiconductor) - SIMPLE SWITCHER Power Converter 150 kHz 0.5A Step-Down Voltage Regulator

LM2594HV, SIMPLE SWITCHER Power Converter 150 kHz 0.5A Step-Down Voltage Regulator

The LM2594/LM2594HV 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.

These devices are available in fixed output voltages of 3.3V, 5V, 12V,

LM2594HV Features

* include a guaranteed ±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 curre
