Introduction

AI Translation

150KHz fixed-frequency PWM DC-DC regulated power converter with 1A output current drive capability, featuring high efficiency, low ripple, high line regulation, and load regulation. Operates in PWM modulation mode with linear duty cycle adjustment over a 0~100% range. Built-in fixed-frequency oscillator and frequency compensation module require minimal external components. Additional integrated features include hysteresis-enabled soft-start, over-temperature protection, overcurrent protection, and secondary overcurrent protection. When secondary overcurrent protection is triggered, the built-in frequency reduction function decreases the operating frequency from 150KHz to 50KHz. This device is a step-down regulated DC power converter designed to convert high-voltage DC input with significant noise and ripple into a low-voltage, low-ripple, low-noise regulated DC output. Available in four versions differentiated by output voltage: 3.3V, 5V, 12V, and an adjustable output voltage version. On-chip integrated protection features include over-temperature protection and current limiting protection.
