The MP3435 from Monolithic Power Systems is a 600 kHz, fixed-frequency, high-efficiency, highly integrated boost converter that operates across a wide input voltage 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 prevents battery depletion. With a configurable input average current limit, the MP3435 supports a wide range of applications.
The MP3435 features a 10 mΩ low-side MOSFET and a 15 mΩ, synchronous high-side MOSFET for high efficiency and low BOM cost. An external compensation pin allows for flexibility when setting loop dynamics and obtaining optimal transient performance under all conditions.
Full protection features include under-voltage lockout (UVLO) protection, switching current limiting and thermal shutdown to prevent damage in the event of an output overload. The MP3435 is available in a low-profile QFN-20 (3 x 4 mm) package.
