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.
