Single-Phase PWM Regulator for IMVP-6.5™ Mobile

CPUs and GPUs

ISL62881, ISL62881B

Features

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

• Precision Core Voltage Regulation

- 0.5% System Accuracy Over-Temperature

- Enhanced Load Line Accuracy

• Voltage Identification Input

Regulator (R ) technology™. Compared with traditional modulators,

the R ™ modulator commands variable switching frequency during

- 7-Bit VID Input, 0V to 1.500V in 12.5mV Steps

- Supports VID Changes On-The-Fly

load transients, achieving faster transient response. With the same

modulator, the switching frequency is reduced at light load,

increasing the regulator efficiency.

• Supports Multiple Current Sensing Methods

- Lossless Inductor DCR Current Sensing

- Precision Resistor Current Sensing

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.

• Superior Noise Immunity and Transient Response

• Current Monitor

• Differential Remote Voltage Sensing

• High Efficiency Across Entire Load Range

• Integrated Gate Driver

• Split LGATE Driver to Increase Light-Load Efficiency (for

ISL62881B)

• Adaptive Body Diode Conduction Time Reduction

• User-selectable Overshoot Reduction Function

• Capable of Disabling the Droop Function

• Audio-filtering for GPU Application

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.

NOTES:

1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on reel specifications.

2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte

tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil Pb-

free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

3. For Moisture Sensitivity Level (MSL), please see device information page for ISL62881, ISL62881B. For more information on MSL please see techbrief

TB363.
