AP1534 - PWM CONTROL 2A STEP-DOWN CONVERTER

Description

AP1534 consists of step-down switching regulator with PWM control.

These devices include a reference voltage source, oscillation circuit, error amplifier, internal PMOS.

AP1534 provides low-ripple power, high efficiency, and excellent transient characteristics.

Features

  • as low current consumption. Since this converter can accommodate an input voltage up to 18V, it is also suitable for the operation via an AC adapter. (Top View) FB 1 8 VSS EN 2 AP1534 7 VSS OCSET 3 6 Output VCC 4 5 Output SO-8 Features.

AP1534 PWM CONTROL 2A STEP-DOWN CONVERTER Description Pin Assignments AP1534 consists of step-down switching regulator with PWM control. These devices include a reference voltage source, oscillation circuit, error amplifier, internal PMOS. AP1534 provides low-ripple power, high efficiency, and excellent transient characteristics. The PWM control circuit is able to vary the duty ratio linearly from 0 up to 99%. This converter also contains an error amplifier circuit as well as a soft-start circuit that prevents overshoot at startup. An enable function, an over current protect function and a short circuit protect function are built inside, and when OCP or SCP happens, the operation frequency will be reduced from 300KHz to 50KHz.
