Overview
SD2503A is a high-efficiency buck DC-DC converter with a fixed 380KHz switching frequency and up to 3A 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 0~100%. It includes enable and output overcurrent protection. During an output short circuit, switching frequency drops from 380KHz to 80KHz. Internal compensation reduces external component count. Available in an SOP8 package.
Applications
- LCD TVs and displays
- Digital photo frames
