  • Description

    The AP1531 is a step-down switching regulator that belongs to the family of integrated circuits (IC) designed for electronic components. The AP1531 has a Pulse Width Modulation (PWM) control circuit that can vary the duty ratio linearly from 0 to 99%. It has an input voltage range of 3.6V to 18V and an output voltage range of 0.8V to VCC. This converter is equipped with an internal PMOS, a reference voltage source, an oscillation circuit, and an error amplifier circuit, which help in achieving low-ripple power, high efficiency, and excellent transient characteristics. In addition, the AP1531 features a soft-start circuit that prevents overshoot at startup, an enable function, and built-in protection functions against overcurrent and short circuits.
