Introduction

ADXL1509 is a 150KHz fixed-frequency PWM DC-DC regulated power converter. It provides 2A output current drive capability, featuring high efficiency, low ripple, high line regulation, and load regulation. The device operates in PWM modulation mode with a duty cycle adjustment range of 0~100%. The ADXL1509 integrates a fixed-frequency oscillator and frequency compensation module, making it extremely easy to use with minimal external components. Additional built-in features include hysteresis-enabled enable control, over-temperature protection, overcurrent protection, and secondary overcurrent protection. When secondary overcurrent protection is triggered, the device's built-in frequency reduction function reduces the operating frequency from 150KHz to 50KHz.
