The buck-boost converter is based on a fixed frequency, pulse width modulation (PWM) controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters power save mode to maintain high efficiency over a wide load current range. The power save mode can be disabled, forcing the converter to operate at a fixed switching frequency. The maximum average current in the switches is limited to a typical value of 1000 m A. The output voltage is programmable using an external resistor divider. The converter can be disabled to minimize battery drain. During shutdown, the load is disconnected from the supply. 2 Applications - Battery voltage regulation (headsets and earbuds, cameras, augmented reality glasses, electronic and robotic toys, personal medical products) - Wi-Fi® or Bluetooth® module supply (IP network camera, wireless access point, single board puter, portable POS, wireless...
