LT3471 OLED Driver

Sep 11th 2014
The LT3471 dual switching regulator combines two 42V, 1.3A switches with error amplifiers that can sense to ground providing boost and inverting capability. The low VCESAT bipolar switches enable the device to deliver high current outputs in a small footprint. The LT3471 switches at 1.2MHz, allowing the use of tiny, low cost ...

7V, 50mW OLED Driver from a 2V to 5.5V input

Mar 17th 2004
The LTC3459 controls peak inductor current when VIN is greater than or less than VOUT. This allows current to be controlled during start-up in a boost application or VOUT to be regulated below VIN when powered from a fresh battery. Peak current control makes the LTC3459 an ideal candidate for charging a back-up source such as ...
