Yu-tai ETA9640PowerSoc + Charging Four chip

A chip to meet mobile power all the features a cleaner look, less BOM cost, greatly improve the production efficiency integrated power display and all depend on the realization of MCU function without lithium protection IC and MOSFET and any other active devices, greatly simplifying the design of mobile power output short program does not lock problem DW01 discharge 1A, 1A boosting efficiency of 90%, small to 2.2uH inductance 5V / 1A synchronous boost efficiency up to 90%, 2MHz switching frequency, inductor small, no-load standby power output ripple small 100uA (excluding USB interfaces dividing resistor power) 1A linear charging, and with input overvoltage protection original single LED, "heartbeat light" display LED power, electricity show energy consumption reduced by 80% overcharge, over discharge, output short circuit protection, short circuit self-recovery, charging the input circuit protection Xiangxi more information, please contact Miss Long:? 18,565,879,459
