To request the full datasheet, please visit www.intersil.com/products/isl95853 Multiphase PWM Regulator for IMVP8в„ў CPUs
ISL95853 Features The ISL95853, fully compliant with Intel IMVP8в„ў
specifications, provides a complete solution for
microprocessor core power supply. It also provides a Voltage
Regulator (VR) with two integrated and one external gate
drivers. The VR can be configured as 3-, 2-or 1-phase,
providing maximum flexibility. The VR uses the serial control bus
(SVID) to communicate with the CPU and achieves lower cost and
smaller board area. Serial data bus Output configurable 3-, 2-or 1-phase using two integrated
gate drivers Precision core voltage regulation
-0.5% system accuracy over temperature
-Enhanced load line accuracy Supports multiple current sensing methods
-Lossless inductor DCR current sensing
-Precision resistor current sensing Based on Intersil’s Robust Ripple Regulator (R3™) technology,
the PWM modulator compared to traditional modulators, has
faster transient settling time, variable switching frequency
during load transients and has improved light load efficiency
with its ability to automatically change switching frequency. Differential remote voltage sensing Programmable VBOOT voltage at start-up Resistor programmable ICCMAX and voltage transition
slew rate The ISL95853 has several other key features. The output
supports DCR current sensing with single NTC thermistor for
DCR temperature compensation or accurate resistor current
sensing. The output comes with remote voltage sense, …
