3 LED Driver
PMP7866: This is an LED driver/converter that can power up to three high output LEDs. It has an input voltage range of 9V-to-16Vin and an output of 10.5Vout @ 1A.
Automotive Range Boost Converter Drives Two Strings of LEDs Reference Design
PMP9010: This wide input voltage range boost operates from an input of 9V - 32V and regulates current in two strings of 13 LEDs. A second control loop monitors and regulates the input current during drop outs or faults. Discrete linear regulators at the bottom of each string control the individual string current while feedback minimizes the output voltage based on the LED voltage mismatch or shorts. This low cost design operates at near 94% efficiency.
MR16 LED Replacement
PMP5665: "PMP5665 is a MR16 halogen bulb replacement with an regulated output current of 350mA at approx. 18V. The design based on TPs40211 works on 12V AC and 7-20V DC."
