Performance introduction
PB0052E imported chip is a complete single-chip mobile power solution with 2.1A switch charging and discharging. The standard lithium battery has three-stage charging, constant voltage and constant current output function, so the whole machine has simple periphery, high reliability and very beautiful performance index. PB0052E's high integration and rich functions, synchronous boost system supports 2.1A output current, conversion efficiency up to 96%, and with constant current output function, when no load, automatically enters sleep state after 8 seconds, quiescent current drops to 20UA Within. Using switch charging technology, providing 2.1A charging current, charging efficiency up to 94%, using standard three-stage, (turbulent / constant current / constant voltage) charging, and built-in IC temperature and input voltage intelligently adjust the charging current, compatible with various Current adapter
