Boost LED Driver with 12V AC and driving 6LEDS at 320mA
PMP7754: This design uses a 12Vac input which is rectified and fed to a boost DC to DC Converter with constant current feedback loop for driving 6 series LEDs at 0.32A. Also implemented is a simple circuit to decode a dimming signal from a TRIAC. This dimming decoder circuit controls the dimming level of the LEDs.
Non-Isolated Synchronous Buck (3.3V@6.4A)
PMP7828.3: This is a synchronous buck converter design with an input voltage range of 10.8V-to-13.2Vin and four regulated outputs: 1Vout@24A, 1.5Vout@30A, 3.3Vout@6.4A, and 1.8Vout@8A.
Non-Isolated Synchronous Buck (1.5V@30A)
PMP7828.2: This is a synchronous buck converter design with an input voltage range of 10.8V-to-13.2Vin and four regulated outputs: 1Vout@24A, 1.5Vout@30A, 3.3Vout@6.4A, and 1.8Vout@8A.
Non-Isolated Synchronous Buck (1.8V@8A)
PMP7828.4: This is a synchronous buck converter design with an input voltage range of 10.8V-to-13.2Vin and four regulated outputs: 1Vout@24A, 1.5Vout@30A, 3.3Vout@6.4A, and 1.8Vout@8A.
