ISL9506
Data Sheet
August 13, 2008
FN6722.0
Multiphase PWM Controller with
Programmable Output Voltage
The ISL9506 is a multiphase PWM buck controller for high
performance digital processor core. This multiphase buck
controller uses interleaved channels to reduce the total output
voltage ripple with each channel carrying a portion of total load
current. The multiple phase implementation results in better
system performance, superior thermal management, lower
component cost, reduced power dissipation, and smaller
implementation area. The ISL9506 multiphase controller
together with ISL6208 external gate drivers provide a complete
solution to power the processor core. The PWM modulator of
ISL9506 is based on Intersil's Robust Ripple Regulator
technology (R 3 ). Compared with the traditional multiphase buck
regulator, the R 3 modulator commands variable switching
frequency during load transients, which achieves faster
transient response. With the same modulator, the switching
frequency is reduced at light load conditions resulting higher
operation efficiency.
ISL9506 responds to LP (Low Power) signal by adding or
dropping PWM2 and adjusting overcurrent protection
accordingly. ISL9506 enables diode emulation and stretches
switching period at light load conditions to improve efficiency.
The diode emulation feature is programmed by DE_EN (Diode
Emulation Enable) and DE_ENN pins.

The ISL9506 has several other key features. ISL9506 reports
output power through a power monitor pin (PMON). Current
sense can be achieved by using either inductor DCR or discrete
precision resistor. In the case of DCR current sensing, a single NTC
thermistor is used to thermally compensate the inductor DCR
variation with temperature. A unity gain, differential amplifier is
