Description

The LM2597HVM-ADJ 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, and an adjustable output version, and are packaged in an 8-lead DIP and an 8-lead surface mount package.This series of switching regulators is similar to the LM2594 series, with additional supervisory and performance features added. LM2597HVM-ADJ Features • 3.3V, 5V, 12V, and adjustable output versions• Adjustable version output voltage range, 1.2V to 37V (57V for HV version)±4% max over line and load conditions• Guaranteed 0.5A output current • Available in 8-pin surface mount and DIP-8 package • Input voltage range up to 60V • 150 kHz fixed frequency internal oscillator• Shutdown /Soft-start • Out of regulation error flag • Error output delay• Bias Supply Pin (VBS) for internal circuitry improves efficiency at high input voltages 23• Low power standby mode, IQ typically 85 μA• High Efficiency and load conditions • Uses readily available standard inductors• Thermal shutdown and current limit protection LM2597HVM-ADJ Applications • Simple high-efficiency step-down (buck)• Efficient pre-regulator for linear regulators• On-card switching regulators• Positive to Negative converter
