Design files

Overview

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 opto-coupler 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.

Features

• Primary Side Regulation (PSR)            
• +/- 1% Voltage Regulation               
• +/- 7.5% Current Regulation
• <70mW Stand-by Power           
• Short Circuit Protection
• High Voltage Startup           
• > 85% Efficiency at 10% load

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
