BU33UV7NUX-EVK-101: 3.3V @ 500mA, 0.6 ~ 4.5V in

Summary

The BU33UV7NUX converter provides a power supply solution for products powered by two-cell alkaline, NiCd, NiMH, one-cell Li-ion, or Li-polymer batteries. It can operate even if the input voltage drops to 0.6V. The BU33UV7NUX has a built-in reset circuit that can be set to detect reset at 1.5V (reset release voltage: 1.9V). When MODE=H, the maximum output current is 500 mA with a current consumption of 13µA. Also, when MODE=L, the maximum output current is 100mA with a current consumption of 7µA. The output voltage is fixed to 3.3V using an internal resistor divider. When the VIN voltage is higher than 3.3V, VOUT matches VIN.
