High Efficiency 400W AC/DC Power Supply Reference Design - PMP11064.1 - TI Tool Folder
PMP11064: PMP11064 is a high-efficiency AC/DC power supply reference design with universal AC input and 20V/20A output. Interleaved transition mode PFC and LLC series resonant converter is applied for 20V/20A main power. A PSR Flyback with MOSFET integrated controller is applied as the auxiliary supply. 91.2% efficiency is achieved at low line and full load. 93.1% efficiency is achieved at high line and full load.
High Efficiency 350W AC/DC Power Supply Reference Design
PMP11303.1: PMP11303 is high-efficiency AC/DC power supply reference design with universal AC input and 25V/13.5A and 12V/1A outputs. LLC+PFC combo IC UCC29950 is applied for the main power stages with 25V/13.5A output while UCC28730 is applied for the auxiliary power with 12V/1A output. This design has low no load power comsumption (152mW@230VAC) and over 93% peak efficiency. This design also meet 80PLUS Gold requirement for 115VAC Internal power supplies.
120VAC Input 5V/200mA Flyback Converter With BJT Switch Reference Design
PMP9059: This reference design creates a 5V at 200mA from a 120VAC Input. This supply is to designed to fit into a very small volume with approximately 10mm total height. The UCC28720 primary side controller with a BJT power switch provides a low cost design. A TPS71433 is also used to provide an additional 3.3V rail. It is important to note the outputs are only functionally (not for safety) isolated from the input.

PMP11303.2: PMP11303 is high-efficiency AC/DC power supply reference design with universal AC input and 25V/13.5A and 12V/1A outputs. LLC+PFC combo IC UCC29950 is applied for the main power stages with 25V/13.5A output while UCC28730 is applied for the auxiliary power with 12V/1A output. This design has low no load power comsumption (152mW@230VAC) and over 93% peak efficiency. This design also meet 80PLUS Gold requirement for 115VAC Internal power supplies.
85 to 265VAC Input 12V/5W Low Cost Flyback with BJT Reference Design
PMP9074: This 12V/5W reference design is optimized for very low cost and yet maintains good efficiency. Two key factors for minimizing cost are a BJT is used for the main power switch, and primary-side regulation eliminates the need for an optocoupler. The UCC28720 quasi-resonant flyback controller is able to implement both of these features. With quasi-resonant switching, efficiency at full load is over 80%, even with a BJT switch. Light-load losses are kept below 100mW due to burst mode operation.
Primary-Side Regulated Flyback with 85 to 265VAC Input (12V @ 0.5A) Reference Design
PMP8787: The PMP8787 reference design uses the UCC28700 flyback controller to generate a 12V/500mA output from a univeral AC input. The primary-side regulation technique implemented by the UCC28700 eliminates the need for an opto coupler, reducing the size and cost of the design. In addition, the valley switching of the UCC28700 allows this design to achieve a maximum load efficiency over 80%; no load losses are less than 40mW. The circuit board measures only 28mm by 33mm, with a maximum height below 20mm.
108VAC-305VAC Input, 3.6V/5mA Flyback Reference Design
PMP9742: This low power flyback supply is designed to minimize the total input current while supplying a low power 3.6V/5mA output. The output is functionally isolated from the input, but not for safety. The physical size is minimized by using the UCC28910 controller with integrated high-voltage MOSFET and primary-side regulation.
350W Constant Voltage - Constant Current (CVCC) Phase-Shifted Full Bridge reference design
PMP9622: This reference design uses the UCC3895 Phase-Shifted Full Bridge controller to implement a high efficiency, 120VAC input to 44Vdc up to 8A output. The power supply is set up to be constant voltage-constant current. The voltage and current are set by fixed resistor values and could be set by micro-processor in the actual product. The design is biased by a low-cost BJT Flyback using the UCC28720 PWM controller.
