SD8910 输入电压4.5V-21V,2A同步整流降压IC
规格书资料详情咨询:13480937849
The SD8906A is a constant frequency, current mode PWM 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 0.6V. The 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 SD8906A is offered in a low profile (1mm)5-pin, thin SOT package, and is available in an adjustable version and fixed output voltage of 1.2V,1.5V, 1.8V,2.5V and 3.3V.
