Constant Voltage/Constant Current power supply generates 5V at 1.5A output at 80% average efficiency with greater than 76% efficiency at 10% load and less than 30mW no load power. The design features primary side regulation (PSR) and integrated flyback switcher. With a low component count and low cost, the design can be used in USB type power supplies for PDAs, tablets, cameras and cell phones.
