LM2576D2T-015

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576D2T-015G is a monolithic integrated circuit step-down switching regulator from the LM2576 series, manufactured by onsemi. It operates with an input voltage range of 4V to 40V and provides a fixed 15V output at up to 3A load current. The device utilizes a 52kHz internal oscillator for PWM control, achieving high efficiency compared to linear regulators. It features thermal shutdown and current limiting protection. The component is housed in a surface-mount TO-263 (D2PAK) package with five pins.
