The Future of Analog IC Technology
MP2935 is a high-efficiency, 4-phase,
synchronous, buck-switching PWM controller
with an SVID interface for high-performance
Intel processors. The multi-phase PWM output
signals can be configured for up to 4-phase
operation with interleaved switching.
MP2935 adopts three-logic-level PWM outputs
for enhanced noise immunity and flexible fault
management. Depending on the power states
set by SVID command, the multi-phase channel
can switch between multiphase and single-
phase operation. In addition, MP2935 supports
programmable load-line resistance. As a result,
the output voltage is always optimally
positioned for a load transient.
The chip also provides accurate and reliable
short-circuit protection with adjustable current
limit threshold and a delayed VR_RDY output
that is masked during on-the-fly output voltage
changes to eliminate false triggering. MP2935
performance is specified over the junction
temperature range of -10°C to 125°C. The chip
is available in 40-lead QFN package.
