降压式转换器
JW5712A
The JW5712/A provides an ultra-low power solution for products powered by either one rechargeable Li-Ion batteries, Li-primary battery chemistries such as Li-MnO2 or two to three cell alkaline batteries. The output voltage of the buck converter is set with three VSEL pins between 0.7V and 3.3V. JW5712/A features low output ripple voltage and low noise with a small output capacitor. Once the input voltage comes close to the output voltage the device enters the 100% duty cycle operation mode to prevent an increase of output ripple voltage. In this operation mode the device stops switching and turns the high-side MOSFET switch on.
JW5712/A is available in 8 ball WLCSP 1.6mmx0.9mm package, which provide a compact solution with minimal external components.
