The AW36099 is a high efficiency synchronous step-up converter with ultra-low quiescent current down to 1μA, it is optimized for battery-powered applications, such as alkaline battery, coin-cell battery, Li-ion or Li-Polymer battery, that requires long battery life and tiny solution size.
The AW36099 uses a hysteretic current mode control scheme with typical 1.4A peak switch current limit when VOUT voltage exceed 2.5V. It consumes 1μA quiescent current under light load condition and can achieve up to 80% efficiency at 100μA load with fixed output voltage versions. 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 AW36099 Operates in down mode and pass-through mode when input voltage is close to or higher than output voltage. In the down mode, the AW36099 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 AW36099 build-in true shutdown function when it is disabled, which isolates the load from the input to reduce the current consumption. Also, the AW36099 integrates OVP, OTP, UVLO protections.
The AW36099 offers both adjustable output voltage version and fixed output voltage versions. It is available in WLCSP 1.245mm x 0.885mm x 0.600mm-6B and DFN 2mm x 2mm x 0.75mm-6L packages.
