Introduction

AI Translation

The XL1509 is a high-efficiency step-down DC-DC converter with a fixed switching frequency of 150KHz, capable of delivering up to 2A output current. It features low ripple, excellent line regulation, and load regulation. The device integrates a fixed-frequency oscillator and frequency compensation circuitry, simplifying circuit design. Its PWM control loop supports linear duty cycle adjustment from 0% to 100%. Built-in enable control and output overcurrent protection are included. When the secondary current limiting function is activated, the switching frequency reduces from 150KHz to 50KHz. The internal compensation block helps minimize external component count. The device is available in ESOP8 and SOP8 packages, with an operating temperature condition of Ta = 25℃.
