85 to 265VAC Input 5V@4A Dual Port Charger For Tablets and Smart Phones Reference Design
PMP8817: 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".
18-36VDCin, 5V/4A Active Clamp Reference Design
PMP10871: The PMP10871 reference design uses the UCC2897A to control an active clamp forward and converts an 18-36V input to an isolated 5V/4A output with efficiency over 92%. This compact design uses only surface mount components.
40V to 60V DC input; 40W Dual output Isolated Flyback Converter (6V@4.33A)
PMP7917.1: PMP7917 is a dual output flyback converter capable of 40W output power. This design uses the LM5021-1 current-mode PWM controller. The operating input voltage range is 40V to 60. The outputs are 6V at 4.33A and 4V at 3.5A. Self-driven synchronous operation is employed for the secondary rectifiers, resulting in good cross regulation.

PMP7917.2: PMP7917 is a dual output flyback converter capable of 40W output power. This design uses the LM5021-1 current-mode PWM controller. The operating input voltage range is 40V to 60. The outputs are 6V at 4.33A and 4V at 3.5A. Self-driven synchronous operation is employed for the secondary rectifiers, resulting in good cross regulation.
Minature 2A Power Supply with LMZ20502 Nano Module - Reference Design
PMP10595: The PMP10595 reference design is a miniature 1.8V, 2A output power supply using the SIMPLE SWITCHER® LMZ20502 nano module. The reference design takes advantage of the miniature package and high level integration of the LMZ20502 to achieve small solution size, which is about 5mm x 6mm (30 sq. mm). The design can supply up to 2A output from an input range of 2.7V to 5.5V. On the reference board the LMZ20502 is set in AUTO mode, and it can achieve good efficiency from light to full load.
85 to 265VAC Input 5V@30W Dual Port Charger For Tablets and Smart Phones Reference Design
PMP10478: This reference design is capable of charging two devices at 2.5A each with over 82% efficiency. The UCC24610 synchronous rectifier controller and CSD17312Q5 FET reduce the rectifier loss and provide high efficiency with a minimal increase in cost. 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 2.15" x 1.7" x 1.0".
