供应致新原装 M1692F51U 同步降压调节器

　　General Description

　　The M1692 is a triple channel high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Supply current during operation is only 50μA/ch and drops to <1μA in shutdown. The 2.5V to 6V input voltage range makes the M1692 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 1.4MHz, 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.
