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.
