AP1513
PWM CONTROL 2A STEP-DOWN CONVERTER
Description
AP1513 consists of step-down switching
regulator with PWM control.
These devices include a reference voltage source, oscillation circuit, error amplifier, and internal PMOS.
AP1513 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 100%.
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 red...
