DESCRIPTION

The LTC®7510 is a digital DC/DC controller with onboard

non-volatile memory and PMBus interface for real time

reporting and control of point-of-load (POL) power

management. Power supply sequencing, margining, turn-

on/-off and fault detection are easily programmed via the

PMBus interface.

The LTC7510 uses a digital control loop which eliminates

external compensation components. The controller sup-

ports current sharing of multiple ICs; up to four controllers

can be synchronized for multiphase operation.

The LTC7510 provides superior accuracy through

internal calibration to correct current sense error

sources upon start-up and programmable temperature

compensation provides accurate current sensing over

temperature. The LTC7510 is available in a 32-lead (5mm

× 5mm) QFN package.
