The BQ25690 is a fully integrated, switch-mode buck-boost charger for 1 cell to 7cell Li-ion or Li-polymer batteries. The wide input voltage range from 2.5V to 34V supports applications powered from batteries, standard USB-PD adapters, and high voltage dedicated DC adapters. The device integrates 4 switching MOSFETs (Q1, Q2, Q3, Q4) and all the loop compensation of the buck-boost converter for small solution size with simple design. The device uses NVDC power path management, regulating the system slightly above the battery voltage without dropping below a configurable minimum system voltage. When system power exceeds the input source rating, battery supplement mode supports the system without overloading the input source. The device also supports the full input (sink) and output (reverse or source mode) voltage ranges for USB Type-C and USB power delivery (USB-PD) applications.
