PMP9166: This reference design uses the TPS54218 in a synchronous buck-boost configuration to generate a negative 0.5V output from a 3.3V input. Switching at 1MHz, the total solution size is extremely compact. An external LM4040 reference provides a precision pull-up voltage and is necessary to regulate the output at a voltage level that is lower than the internal reference of the controller.
PMP9144: This reference design provides an isolated 14.5V/35W output from a universal 85-265VAC input. It uses the UCC28740 flyback controller to provide high efficiency and minimize light load losses. Maximum load efficiency is over 88%. The average efficiency (measured at 25%, 50%, 75%, and 100% load) is 87.9%. The UCC28740 also provides accurate current limiting which eliminates the need for a load protecting switch on the output.
PMP9715: This reference design provides an isolated 12V/36W output from a universal AC input range with over 89% peak efficiency. The UCC24610 synchronous rectifier controller and CSD19531Q5A FET reduce the rectifier loss and provide high efficiency with a minimal increase in cost. The UCC28740 flyback controller uses a combination of peak current modulation and frequency modulation to maintain excellent efficiency at lighter loads and minimize no load power consumption. The current regulation feature of the UCC28740 provides accurate current limit protection. This compact design consumes a volume of only 2.0" x 2.0" x 0.75".
PMP11135: The PMP11135 reference design uses the UCC28711 to provide an isolated 13.5V at 0.9A output. The UCC28711 implements primary-side regulation, eliminating the need for an opto-coupler and reducing the size and cost of the design. This design meets Class B conducted emissions without the need for a common mode input choke.
PMP10351: This reference design uses the UCC28713 primary-side regulated (PSR) flyback controller to generate a 12V/1.5A output from a univeral AC input. The valley switching of the UCC28713 allows this low-cost design to achieve an average efficiency over 87%; no load losses are less than 50mW. The PSR function eliminates the need for an optocoupler and TL431, greatly simplifying the circuit and reducing cost.
PMP9730: The PMP9730 reference design employs the UCC28051 power factor correction controller to implement a single stage PFC-Flyback AC/DC converter that generates an isolated 12V output at 3A from a universal AC input. The design features UCC28910 primary side regulation Flyback switcher for generating the VDD bias rails and the UCC24610 for 2ndary side synchronous rectification. This provides an excellent solution for systems such as motor drives requiring an isolated bus voltage, good power factor and high efficiency.
PMP11124: The PMP11124 reference design uses the UCC28700 and TPS25810 to provide an isolated 5V at 3A over a USB type C interface. The UCC28700 implements primary-side regulation, eliminating the need for an opto-coupler and reducing the size and cost of the design. Cost is further minimized by using an output diode instead of a synchronous rectifier.
