Full Bridge Gate Driver with Boost Convertor



General Description

LP1115 consists of two parts: Full Bridge Gate Drive and Boost Convertor. The Full Bridge Driver part of LP1115 is a single phase 12V MOSFET gate driver optimized to drive the gates of both high-side and low-side power MOSFETs in a synchronous buck converter. The Boost Convertor part of LP1115 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 3A current power MOSFET makes this converter highly power efficiently. The LP1115 implements a constant frequency 1MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component sizes.
