AP1510 consists of step-down switching regulator
with PWM control. These devices include a reference
voltage source, oscillation circuit, error amplifier,
internal PMOS and etc.
AP1510 provides low-ripple power, high efficiency,
and excellent transient characteristics. The PWM
control circuit is able to very 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.
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
DataSheet4pmUoi.nrctia-opbmaleckadgeevi,cpersovwidhinegn
coupled with the SOP–8L
such outstanding features as
low current consumption. Since this converter can
accommodate an input voltage of up to 23V, it is also
ideal when operating via an AC adapter.
