PMP8817 Reference Design

Texas Instruments

85 to 265VAC Input 5V@4A Dual Port Charger For Tablets and Smart Phones Reference Design

Description

This reference design is capable of charging two devices at 2A each with over 85% efficiency. The UCC24610 synchronous rectifier controller and CSD18533Q5A FET reduce the rectifier loss and provide ultra-high efficiency with a minimal increase in cost. The UCC28700 primary-side regulated flyback further minimizes cost by eliminating the need for an opto-coupler: and yet maintains good output regulation. The TPS2561A provides accurate and independent current limit protection for each port. The TPS2513 communicates with the mobile device under charge to ensure that the charger is accepted by most phone and tablet models. This compact design consumes a volume of only 1.5 x 1.8" x 0.9"."
