ISL62881B规格书详情
The ISL62881 is a single-phase PWM buck regulator for
miroprocessor or graphics processor core power supply. It uses an
integrated gate driver to provide a complete solution. The PWM
modulator of ISL62881 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 ISL62881 can be configured as CPU or graphics Vcore controller
and is fully compliant with IMVP-6.5™ specifications. It responds to
DPRSLPVR signals by entering/exiting diode emulation mode. It
reports the regulator output current through the IMON pin. It senses
the current by using either 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.
Maintaining all the ISL62881 functions, the ISL62881B offers
VR_TT# function for thermal throttling control. It also offers the
split LGATE function to further improve light load efficiency.
