| 供应G5728TO1U-1MHz 1A同步降压调节器 现货 |
台湾致新 G5728TO1U TSOT-23-5 代理商主推
General Description
The G5728 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 G5728 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.
