SYR837 - Synchronous Step Down Regulator

Description

SYR837/SYR838 is a high efficiency 2.4MHz synchronous step down DC/DC regulator IC capable of delivering up to 6A output currents.

It can operate over a wide input voltage range from 2.6V to 5.5V and integrate main switch and synchronous switch with very low RDS (ON) to minimize the conduction loss.

Features

Input voltage range: 2.6V to 5.5V.
2.4 MHz switching frequency minimizes the external components.
Typical 65uA quiescent current.
Low RDS(ON) for internal switches (PFET/NFET): 28mΩ/17m.
