2A 24V 340kHz synchronous Buck Converter

Features

General Description

• Wide Input Voltage from 4.5V to 24V

APW7334 is a 2A synchronous buck converter with inte-

• 2A Continuous Output Current

grated power MOSFETs. The APW7334 design with a cur-

• Adjustable Output Voltage from 0.8V to 20V

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

• Intergrated High/Low Side MOSFET

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

• PFM/PWM mode Operation

• Fixed 340kHz Switching Frequency

0.8V to 20V to provide excellent output voltage regulation.

The APW7334 is equipped with an automatic PFM/PWM

mode operation. At light load, the IC operates in the PFM

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