The LTC4269 is essentially an LTC4265 PD controller with an onboard, high efficiency switcher for designs requiring a more integrated solution offered in a compact 32-pin 7mm x 4mm DFN package. They are compatible with both “af” (Type 1) and “at” (Type 2) hardware and support 2-event classification. The LTC4269 offers an auxiliary input which shuts down the controller when the PD is plugged into a wall socket or battery.
