Overview

SD7005 is a high-efficiency, high-voltage buck DC-DC converter with a fixed 150KHz switching frequency and up to 0.4A output current. It provides low ripple and excellent line and load regulation. The integrated fixed-frequency oscillator and frequency-compensation circuit simplify design. The PWM loop linearly adjusts duty cycle from 0~90%. Output overcurrent protection reduces switching frequency from 150KHz to 45KHz during an output short circuit. Internal compensation reduces external component count. Available in ESOP8 and SOP8 packages.

Applications

• Power supply for electric-vehicle controllers
