... as ringed in red. The lower device is an SMPS controller LCT.PB456, 36v in, 5v out at approx 0.3 - 0.5A. Its in a 10pin package. Pin 3 is Vin, pin 2 is SW and pin 8 is FB. The upper device, 59TA0, is, I believe, a p-channel MOSFET. source on pin 4, drain on pins 1, 2, 5 and 6 and gate on pin 3.

Despite extensive searching I haven't been able to get meaningful hits on either part # that match physically. Anyone?

OK, I've found the MOSFET... its an gsm3459 (globaltech semiconductors) or an AFP3459 (ALFA-mos Technology). PMOS 60v, 5A
