Overview
SYR828 High Efficiency 5.
5V, 6A, 2.
4MHz I2C Programmable, Synchronous Step Down Regulator Preliminary Specification General Description SYR828 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.
The output voltage can be programmed from 0.
7125V to 1.
5V through I2C interface.
SYR828 is in a space saving, low profile CSP1.
56*1.
