The AP1534 consists of step-down switching regulator with PWM control. These devices include a reference voltage source, oscillation circuit, error amplifier, internal PMOS.
The 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 overcurrent 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. Also, an internal compensation block is built in to minimize external component count.
With the addition of an internal P-channel Power MOS, a coil, capacitors, and a diode connected externally, these ICs can function as step-down switching regulators. They serve as ideal power supply units for portable devices when coupled with the SO-8 mini-packages, providing such outstanding 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.
