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. 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.
