1 / 10 page  LP1115-01 Dec.-2019 Email: marketing@lowpowersemi.com www.lowpowersemi.com Page 1 of 10 Preliminary Datasheet LP1115 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. Order Information LP1115 F: Pb-Free Package Type QV: QFN-20 Feedback Voltage Default: 0.6V A: 1.24V 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 Marking Information Device Marking Package Shipping LP1115QVF LPS LP1115 YWX QFN-20 (4mm*4mm) 3K/REEL LP1115AQVF LPS LP1115A YWX QFN-20 (4mm*4mm) 3K/REEL Marking indication: Y:Production year W:Production week X: Series Number |
