120 VAC 7W PFC Wall Dimmable AC Linear Floating Switch LED Driver Reference Design
PMP6022: This magnetic-free (no transformer/inductor), small form-factor, LED driver circuit is ideal for use in LED lamps, downlights, and fixtures. The design takes advantage of relatively new high forward-voltage (22V), low-current (20mA) white LEDs to realize a compact design producing >800 lumens from about 9W of input power. The novel floating switch architecture produces low LED current ripple comparable to single-stage SMPS based designs while providing excellent compatability with a wide range of common household wall dimmers.
85-265VACin, 24V/0.7A, 5V/0.25A
PMP5536: The PMP5536 is a quasi-resonant isolated flyback; the input voiltage is the universal range and two outputs provide 5V @ 250mA, from an LDO, and a regulated 24V @ 700mA, 2.5A peak for 30milliseconds.
9Vdc-57Vdc Input, 56V/20W Isolated Flyback
PMP6963: This reference design uses the TPS40210 current mode controller to generate an isolated 56V/0.35A output from a wide 9V - 57V DC input. This design uses diode rectification on the output stage and achieves efficiencies up to 89% at full load with peaks over 90%.
220VAC in 28W Non-Isolated T8 Tube LED Driver Solution
PMP4362: The reference design presents non-isolated LED driver solution for 28W T8 tube application. The valley switching mode controller TPS92314 is used to achieve high effiency (>93%) over input range. Inherent PFC achieves high PF>0.92. The design includes EMI driver board and LED driver board. The overall size is around 100mmx16mmx14.5mm.
85 -265V AC in, 24V/0.7A, 5V/0.25A AC/DC Open Frame Power Supply
PMP7148.2: This reference design is a quasi-resonant isolated flyback. The input voltage is the universal 85 - 265V AC range and two outputs provide 5V @ 250mA, from an LDO, and a regulated 24V @ 700mA, 2.5A peak for 30milliseconds, employing the UCC28600D Flyback controller.
20W AC/DC PSR isolated LED Driver for T8
PMP4330: This reference design demonstrates low cost, high PF LED Driver solution for T8, which includes single stage Flyback with Primary Side Regulation topology using TPS92310. The input range is 85~265Vac and output is 38~42V 420mA or 26~42V 420mA
Flyback for Audio/Video Control
PMP2915: This low-power (3W) off-line isolated flyback regulator produces dual +12V/+24V outputs. Output voltage cross-regulation is excellent due to the use of a linear regulator on the 12V output and direct feedback on the 24V output.
