PMP9208, 65W (130W Surge) Flyback Power Supply for Laptop Adapter Apps w/85-265VAC Input Reference Design. The PMP9208 is a power adapter reference design for 19.5V output, constant voltage / constant current, 65W flyback power supply with 130W surge capability. Primary side regulation eliminates feedback Optocoupler and provides 1% regulation down to no-load. Average efficiency of > 89% and no load power of < 70mW are achieved. 0 - 100% load transients enabled by a secondary side fast wake up circuit
