Divide-by-2 and -3, 10A Charge Pump, Capacitor Divider
The PE25213 is an ultra-high efficiency charge pump that is configurable to divide down an input voltage by two or three and delivers up to 10A with peak efficiency up to 99%.
The PE25213 supports an input voltage range of 5.7V to 15V in divide-by-2 mode and 8.4V to 15V in divide-by-3 mode. The PE25213 is primarily used as a front-end converter to convert a two- or three-cell battery input to a 1-1.5S output for downstream regulator to improve overall system efficiency and extend run time.
The PE25213 offers a unique auto-switch mode to change the divide-down ratio during operation to avoid a downstream under-voltage lockout (UVLO) event at heavy system loading during low battery condition.
The PE25213 comes in a 4.545 mm × 2.715 mm 47-pin WLCSP package. The pinout is specially designed to be fully compatible with Type III PCB design.
