Application Note: AN_SYR837/SYR838 High Efficiency 5.5V, 6A, 2.4MHz I 2 C Programmable, Synchronous Step Down Regulator
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. The output voltage can be programmed from 0.7125V to 1.5V through I2 C interface. SYR837/SYR838 is in a space saving, low profile CSP1.56*1.96-20 package（點擊即可咨詢芯片詳細信息）.
