Product Summary

The LM2575HVT-ADJ is a member of LM2575 series. It is available in TO-220 package. The series is a kind of monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V, 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 fixed-frequency oscillator. The typical applications include: (1)Simple high-efficiency step-dow(buck) regulator; (2)Efficient pre-regulator for linear regulators; (3)On-card switching regulators; (4)Positive to negative converter (Buck-Boost).

Parametrics

Features: (1)3.3V, 5V, 12V, 15V, and adjustable output versions; (2)Adjustable versiooutput voltage range, 1.23V to 37V (57V for HV version) ±4% max over line and load conditions; (3)Guaranteed 1A output current; (4)Wide input voltage range, 40V up to 60V for HV version; (5)Requires only 4 external components; (6)52 kHz fixed frequency internal oscillator; (7)TTL shutdowcapability, low power standby mode; (8)High efficiency; (9)Uses readily available standard inductors; (10)Thermal shutdowand current limit protection; (11)P+ Product Enhancement tested.
