　　General Description

　　The G5719 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 G5719 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.
