AP1510 consists of step-down switching regulator with PWM control.
These devices include a reference voltage source, oscillation circuit,
error amplifier, and internal PMOS.
AP1510 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
reduced from 300KHz to 30KHz. Also, an internal compensation
block is built in to minimum external component count.
