LP6284 Datasheet | Lowpowersemi

Preliminary Datasheet Multi-Channel DC-DC Converter General Description The LP6284 includes a high-performance boost regulator, a low dropout linear regulator (LDO), a gate pulse modulator (GPM), a voltage detector, a V buffer (unity-gain OPA), and a VGH charge pump controller for active matrix TFT LCDs. The converter is a high switching frequency (640kHz or 1.2MHz) current-mode regulator with an integrated 16V N-Channel 0.2Ω MOSFET that allows the use of ultra-small inductors and ceramic capacitors. It provides fast transient response to pulsed loading while achieving efficiency over 90%. The low-dropout (LDO) linear regulator can supply up to 350mA current while input voltage...
