MP3435 - Synchronous Boost Converter

Description

The MP3435 is a 600kHz, fixed frequency, high-efficiency, highly integrated boost converter that operates across a wide input voltage (VIN) range, with optional input disconnect and an input average current limit function.

Features

  • 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 allows flexibility in setting loop dynamics and obtaining optimal transient performance under all conditions. The MP3435 includes under-voltage lockout (UVLO), switching current limiting, and thermal shutdown to prevent damage in the event of an output overload. The MP3435 is available in a low-profile QFN20 (3mmx4mm) package.

MP3435 19A, 600kHz, 22V Output Range, Synchronous Boost Converter with Input Disconnect Function DESCRIPTION The MP3435 is a 600kHz, fixed frequency, high-efficiency, highly integrated boost converter that operates across a wide input voltage (VIN) range, with optional input disconnect and an input average current limit function. The input disconnect feature provides additional protection by isolating the input from the output during an output short or shutdown. For battery-operated applications, this feature also helps prevent battery depletion. With a configurable input average current limit, the MP3435 supports a wide range of applications. The MP3435 features a 10mΩ low-side MOSFET (LS-FET) and a 15mΩ synchronous high-side MOSFET (HS-FET) for high efficiency and low BOM cost.
