Overview

The 1509 is a fixed-frequency 150KHz PWM DC-DC switching regulator with 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 linearly adjustable duty cycle ranging from 0 to 100%. It integrates a fixed-frequency oscillator and frequency compensation module, requiring minimal external components. The chip also incorporates enable control with hysteresis, over-temperature protection, over-current protection, and secondary over-current protection. When secondary over-current protection is triggered, the built-in frequency reduction function reduces the operating frequency from 150KHz to 50KHz.

Applications

LCD TVs and displays
Digital photo frames
Set-top boxes
