The CC5161D is a constant band, current mode step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell Lithium-lon (Li+) battery. The output voltage can be regulated as low as 0. 6V. The CC5161D can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load.
The CC5161D is offered in a low profile 6-pin, DFN package, and is available in an adjustable version.
