The BQ25692-Q1 is a fully-integrated, switch-mode buck-boost charger for 1 cell to 7 cell 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 four switching MOSFETs (Q1, Q2, Q3, Q4) and all the loop compensation of the buck-boost converter for small design size with simple design. 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.
