General Description
The G5725 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 G5725 ideally
suited for single Li-Ion battery-powered applications.
100% duty cycle provides low dropout operation, ex-
tending 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.
