PMU-CN8913

The CN8913 is a 3-Channel PMU that includes high efficiency synchronous 38V buck converter with 42V input standoff voltage, low startup high efficiency boost converter and a high accuracy super capacitor charger. A HV buck outputs fixed-3.3V/800mA saving external resistor divider. The boost converter could provide up to 12V/450mA output from super capacitor or other backup power supply at 2.5V. Boost output is set by external resistors. Supercapacitor constant voltage charging voltage is 2.55V. The CN8913 also employs cycle by cycle current limit and hiccup OCP and Input OVP protections, as well as thermal shutdown. The CN8913 is available in ESOP8L and DFN3X3-10L with exposed Thermal and GND pad.
