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.
