APW7304

4A 24V 340kHz synchronous Buck Converter

Features

General Description

• Wide Input Voltage from 4.5V to 24V

APW7304 is a 4A synchronous buck converter with inte-

• 4A Peak Output Current

grated power MOSFETs. The APW7304 design with a cur-

• Adjustable Output Voltage from 0.8V to 20V

rent-mode control scheme, can convert wide input volt-

• Intergrated N-MOSFET

age of 4.5V to 24V to the output voltage adjustable from 0.

• Fixed 340kHz Switching Frequency

8V to 20V to provide excellent output voltage regulation.

The APW7304 is equipped with an automatic PFM/PWM

• Stable with Low ESR Ceramic Output Capacitors mode to reduce the switching losses. At heavy load, the

• Power-On-Reset Detection

IC works in PWM.

• Programmable Soft-Start

The APW7304 is also equipped with Power-on-reset, soft-

• Over-Temperature Protection

start, and whole protections (over-temperature, and cur-

• Current-Limit Protection with Frequency Foldback rent-limit) into a single package.

• Enable/Shutdown Function

• Small SOP-8P Packages

This device, available SOP-8P, provides a very compact

system solution external components and PCB area.
