代理商供应 致新 G5737F11U 电源芯片

　　General Description

　　The G5737 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Supply current during operation is only 50μA and drops to <1μA in shutdown. The 2.5V to 6V input voltage range makes the G5737 ideally suited for single Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending

　　battery run time in portable systems. Switching frequency is internally set at 1MHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increase efficiency and eliminates the need for an external Schottky diode. Built-in soft start function eliminates in-rush current that could damage the system.
