specifications. it responds to psi# and dprslpvr signals by adding or dropping phase 2, 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 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 unique split lgate function further increases light load efficiency. 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. the isl62882c offers the fb2 function to optimize 1-phase performance. pricing / packaging / samples / ordering ibuy direct from intersil ibuy direct - out of stock request samples check distributor inventory available in rohs/pb-free part no. design-in status temp. package msl price us $ isl62882ceval2z active eval board n/a contact us isl62882chrtz active hi-temp comm 40 ld tqfn 13.93 ISL62882CHRTZ-T active hi-temp comm 40 ld tqfn t+r 13.93 isl62882cirtz active ind 40 ld tqfn 14.32 isl62882cirtz-t active ind 40 ld tqfn t+r 14.32 the price listed is the manufacturer's suggested retail price for quantities of 1k units. however, prices in today's market are fluid and may change without notice. msl = moisture sensitivity level - per ipc/jedec j-std-020 smd = standard microcircuit drawing technical documentation datasheet(s): to request a copy of this datasheet please email majid kafi at mkafi@intersil.com evaluation board(s): isl62882ceval2z user guide isl62882eval2z user guide tools and support isim design simulation no models available application block diagrams desktop computers notebook computers pos register pos self-service applications notebook core voltage regulator notebook gpu voltage regulator related devices parametric table isl6217 pwm controller for intel pentium m isl6217a pwm controller, imvp license required, cpu power for centrino isl6219a microprocessor core voltage regulator precision multiphase buck pwm controller for mobile applications isl6244 multiphase pwm controller isl6247 multiphase pwm controller for mobile intel pentium 4 isl62882 multiphase pwm regulator for imvp-6.5? mobile cpus and gpus pa g e 2 of 3 isl62882c multiphase pwm re g ulator for imvp-6.5? mobile cpus and gpus 2/17/2011 htt p ://www.intersil.com/ p roducts/ p rint.as p ?id=isl62882c
