AW360997DNR中文资料Synchronous Step-up Converter with Ultra Low Quiescent Current数据手册Awinic规格书

描述 Description

The AW360997 is a high efficiency synchronous step-up converter with ultra-low quiescent current down to 1μA.
The AW360997 uses a hysteretic current mode control scheme with typical 1.4A peak switch current limit. It consumes 1μA quiescent current under light load condition and can achieve up to 80% efficiency at 100μA load. It support up to 350mA output current when input voltage is between 2.8V and 5V, and achieve up to 93% efficiency at 200mA load.

The AW360997 Operates in down mode and pass-through mode when input voltage is close to or higher than output voltage. In the down mode, the AW360997 will continue to regulate the output voltage even when the input voltage exceeds the output voltage. When VIN > VOUT + 0.37V, It enters pass-through mode and the device stops switching. The rectifying PMOS constantly turns on and low-side switch constantly turns off.

The AW360997 build-in true shutdown function when it is disabled, which isolates the load from the input to reduce the current consumption. Also, the AW360997 integrates OVP, OTP, UVLO protections.

The AW360997 has a 5V fixed output voltage. It is available in WLCSP 1.245mm x 0.885mm x 0.600mm-6B and DFN 2mm x 2mm x 0.75mm-6L packages.
