ISL62883B规格书详情
The ISL62883 is a multiphase PWM buck regulator for
miroprocessor core power supply. The multiphase buck converter
uses interleaved phase to reduce the total output voltage ripple with
each phase carrying a portion of the total load current, providing
better system performance, superior thermal management, lower
component cost, reduced power dissipation, and smaller
implementation area. The ISL62883 uses two integrated gate
drivers and an external gate driver to provide a complete solution.
The PWM modulator is based on Intersil's Robust Ripple Regulator
(R3) technology™. Compared with traditional modulators, the R3™
modulator commands variable switching frequency during load
transients, achieving faster transient response. With the same
modulator, the switching frequency is reduced at light load,
increasing the regulator efficiency.
The ISL62883 is fully compliant with IMVP-6.5™ specifications. It
responds to PSI# and DPRSLPVR signals by adding or dropping
PWM3 and Phase-2 respectively, adjusting overcurrent protection
threshold accordingly, and entering/exiting diode emulation mode.
It reports the regulator output current through the IMON pin. It
senses the current by using either a discrete resistor or inductor
DCR whose variation over temperature can be thermally
compensated by a single NTC thermistor. It uses differential
remote voltage sensing to accurately regulate the processor die
voltage. The adaptive body diode conduction time reduction
function minimizes the body diode conduction loss in diode
emulation mode. User-selectable overshoot reduction function
offers an option to aggressively reduce the output capacitors as
well as the option to disable it for users concerned about
increased system thermal stress. In 2-Phase configuration, the
ISL62883 offers the FB2 function to optimize 1-Phase
performance.
The ISL62883B has the same functions as the ISL62883, but
comes in a different package.
