AP5004 is a PWM controlled 2.5A step-down converter. It has an input voltage range of 10V to 32V and an adjustable output voltage range of 0.8V to 6V. It features PWM control with a duty ratio of 0% to 90%, a typical oscillation frequency of 300KHz, a short circuit protect frequency of 50KHz, a maximum standby current of 2uA, current limit and enable functions, thermal shutdown function, and a built-in internal N-channel MOS. The AP5004 provides low-ripple power, high efficiency, and excellent transient characteristics. It is suitable for high power system applications due to its high input voltage (32V), output current (2.5A), and small SOP-8L package size.
The AP5004 from Diodes Incorporated is a PWM‑controlled step‑down (buck) converter that delivers up to 2.5 A with an input range of 10 V to 32 V and an adjustable output of 0.8 V to 6 V. It integrates a built‑in N‑channel MOSFET, over‑current, short‑circuit and thermal‑shutdown protection, and operates at a typical 300 kHz switching frequency.
Typical applications include microprocessor core supplies, networking, LCD/TV, and telecom power. The device is supplied in a RoHS‑compliant SOP‑8L package and can be ordered as AP50048G‑13 with tape‑and‑reel packaging.

The device operates with an input voltage from 10 V to 32 V.
It can deliver up to 2.5 A of output current.
When a short‑circuit occurs, the switching frequency drops from 300 kHz to 50 kHz.
The standby current is approximately 2 µA.
