AP5004SG-13, Импульсный понижающий DC-DC стабилизатор, регулируемый, 10В-32В (Vin), 800мВ-6В, 2.5А, SOIC-8

The AP5004SG-13 is a PWM Control Step-down Converter that includes a reference voltage source, oscillation circuit, error amplifier and an 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%. This converter also contains an error amplifier circuit as well as a soft-start circuit that prevents overshoot at start-up. 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 to 50kHz. Also, an internal compensation block is built in to minimum external component count. With built-in power NMOS, a step-down switching regulator can easily be built by adding a coil, capacitors and a diode.
