310W PSU Using Transition Mode Bridgeless PFC and LLC-SRC - Reference Design
PMP9640: High efficiency, high power factor and reliable power supply are the main focus of the PMP9640 design for motor driver applications. Low cost analog transition mode (TM) PFC controller UCC28051 has been used for bridgeless PFC as the first conversion stage of the PMP9640. LLC series resonant converter (SRC) with UCC25600 is applied as the second stage of the PMP9640. In addition, a high-side buck converter with UCC28710 is applied here as the bias supply. In this design, bridgeless PFC efficiency can go up to 98.5%.
85-265Vin, 5Vout, 1Aout, AC-DC Fly-Buck Converter Reference Design
PMP10834: The PMP10834RevA reference design is a compact and thermally efficient design intended to step down a wide range of AC inputs (85VAC to 265VAC). This non-isolated Flybuck design incorporates the UCC28C42 PWM with an optocoupler feedback to provide 1% output voltage regulation. All the circuit components (including magnetics) are standard parts.
350W PSU with Universal AC Input and 28V Output - Reference Design
PMP9531: High efficiency, high power factor and reliable power supply are the main focus of the PMP9531 design for motor driver applications. Transition mode (TM) power factor correction (PFC) with UCC28051 and LLC series resonant converter (SRC) with UCC25600 are applied in PMP9531. In addition, a high-side buck converter with UCC28710 is applied here as the bias supply. 93% converter efficiency is achieved at high line while still obtaining 90% converter efficiency at low line.
Low-Line Wide Input LLC Resonant Conv for Consumer Electronics (12V@10A) Reference Design
PMP8762: The PMP8762 reference design provides a 12V/10A output from a low line-input voltage (100Vac to 132Vac) with a single LLC resonant converter stage. This design is featured with its low circuit cost, low electromagnetic interference (both conduction and radiation), and high efficiency (over 87% @ full load). This design uses the UCC25600 resonant converter controller along with UCC27702 high side gate driver to control the LLC resonant converter.
Reference Design - Universal Line Input AC-DC 3W High Side Buck Converter using UCC28720
PMP9649: The PMP9649 reference design is a simple, low-cost high side Buck converter to convert universal AC input voltage (85Vac to 265Vac) to a non-isolated 20V/150mA DC output with UCC28720 controller. BJT is applied as the buck switch for cost optimization, and simplicity is achieved with bulit-in sample and hold regulation function in UCC28720.
Universal AC-DC Buck Converter Using UCC28710 Reference Design
PMP9530: The PMP9530 reference design uses a buck converter to convert universal AC input voltage (85Vac to 265Vac) to a 18V/300mA DC output with UCC28710 controller. High efficiency and circuit simplicity is achieved with quasi-resonant valley-switching operation and a Buck topology.
