TCS4131
1uA Ultra-Low Quiescent Current,1.3A Outpt Synchronous BUCK
产品描述
The TCS4131 is a constant frequency, 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-Ion (Li+) battery. The output voltage can be regulated as low as 1.13V.
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 TCS4131 is offered in a low profile 5-pin, SOT package, and is available in an adjustable version.
