Monolithic Power Systems (MPS) MP3435 Synchronous Boost Converters are 600kHz, fixed frequency, high-efficiency, highly integrated boost converters. The MP3435 operates across a wide input voltage range of 3V to 20V, with an optional input disconnect and an input average current limit function. The input disconnect feature on the device offers additional protection by isolating the input from the output during an output short or shutdown. Additionally, this feature helps prevent battery depletion for battery-operated applications. The device supports various applications via a configurable input average current limit.
The MPS MP3435 Synchronous Boost Converters integrate a 10mΩ low-side MOSFET (LS-FET) and a 15mΩ synchronous high-side MOSFET (HS-FET) for high efficiency and low BOM cost. An external compensation pin enables flexibility in setting loop dynamics and obtaining optimal transient performance under all conditions. Further features include under-voltage lockout (UVLO), switching current limiting, and thermal shutdown to prevent damage in the event of an output overload.
The MP3435 is housed in a low-profile QFN20 (3mm x 4mm) package.
