LP1115 Full Bridge Gate Driver with Boost Convertor Preliminary Datasheet
●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.
■Features:
●Full Bridge Driver
◆All-In-One Synchronous Buck Driver
◆Bootstrapped High-Side Drive
◆One PWM Signal Generates Both Drives
◆Anti-cross Conduction Protection Circuitry
●Boost Convertor
◆Up to 94% efficiency
◆Shut-down current:1uA
◆Input and Output voltage Up to 24V
◆Internal Compensation, Soft-start
◆1MHz fixed frequency switching
◆High switch on current: 3A
