CM3706A
1.
5MHz, 600mA Synchronous Step-Down
Regulator
GENERAL DESCRIPTION
The CM3706A is a high efficiency monolithic synchronous buck
regulator using a constant frequency, current mode architecture.
The device is available in an adjustable version.
Supply current with no load is 300uA and drops to 1uA in shutdown.
The 2.
5V to 6.
5V input voltage range makes the CM3706A ideally suited for single Li-Ion, two to four AA battery-powered applications.
100% duty cycle provides low dropout operation, extending battery life in portable systems.
PWM pulse skipping mode operation provides very low output ripple voltage for noise sensitive applications.
Switching frequency is internally set at 1.
