Two-Switch Buck-Boost Converter for 24W Wide Input
PMP7995: PMP7995 is a buck-boost converter rated for 12V output at 2A from an input voltage of 5V to 60V. This design uses the LM5118 buck-boost controller at a switching frequency of 300 kHz. To minimize cost the layout was done for a 2 layer printed circuit board.
Small Form Factor 10W Offline Flyback Power Supply Reference Design
PMP9517: The PMP9517 is a high density constant voltage / constant current power supply with an 85VAC-265VAC input range and 5V/10W outptut. The design features primary side regulation (PSR) of a low cost power transistor (BJT). With low component count and low cost, the design is suitable for USB type power supplies used in smart phones, tablets, PDAs or digital cameras. This design is similar to PMP9135 but with a smaller overall size.
120W Automotive Two-Switch Buck-Boost Converter
PMP7905: PMP7905 is a two-switch buck-boost converter capable of 120W output power. This design uses the LM5118 wide voltage range buck-boost controller. 100V Schottky rectifiers and MOSFET are used for input switching, while 30V Schottky rectifiers and MOSFET are used for output switching. The operating input voltage range is targeted for automotive applications as 8V to 16V with 75V transient capability.
30 to 350Vin 15Vout @ 1A Isolated Flyback Converter Reference Design
PMP9334: PMP9334 is an isolated Flyback converter utilizing the LM5022 for industrial applications. It uses primary side regulation from an auxiliary winding with a resistor divider network to the Feedback pin of the LM5022. This design has a minimum operating input voltage of 30V and a max rating of 350V.
