Ordering Information
General Description
AP5004 consists of step-down switching regulator with PWM
control. These devices include a reference voltage source,
oscillation circuit, error amplifier, internal NMOS.
AP5004 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 90%. 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 300 KHz to 50 KHz. Also, an
internal compensation block is built to minimize external
component count.
With built-in power NMOS, a step-down switching regulator is
easy to be built by adding a coil, capacitors and a diode.
The high efficiency, low standby current, high input voltage (32V)
and output current (2.5A) combining with small SOP-8L package
give AP5004 unprecedented advantage in high power system
applications.
