AP1530 consists of step-down switching regulator with PWM
control. These devices include a reference voltage source,
oscillation circuit, error amplifier and internal PMOS.
AP1530 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. An enable function, an over
current protection and a short circuit protection 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 minimum 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
SOP-8L package, 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.
