FN9177.0

Single Phase PWM Controller for Mobile

Graphical Processing Unit (GPU)

Features

• High performance synthetic ripple regulation

The ISL6269 IC is a Single-Phase Synchronous-Buck PWM

• Extremely fast transient response

controller featuring Intersil's Robust Ripple Regulator (R )

technology that delivers truly superior dynamic response to

input voltage and output load transients. Integrated

MOSFET drivers, 5V LDO, and bootstrap diode result in

fewer components and smaller implementation area.

• External type-two loop compensation

• ±1% regulation accuracy: -10°C to +100°C

• Starts into a pre-biased output

Intersil’s R technology combines the best features of fixed-

• Wide input voltage range: +7.0V to +25.0V

• Wide output voltage range: +0.6V to +3.3V

• Wide output load range: 0A to 25A

frequency PWM and hysteretic PWM while eliminating many

of their shortcomings. R technology employs an innovative

modulator that synthesizes an AC ripple voltage signal V ,

analogous to the output inductor ripple current. The AC

• Programmable PWM frequency: 200kHz to 600kHz

• Power good monitor

signal V enters a hysteretic comparator where the lower

threshold is the error amplifier output V

, and the upper

COMP

threshold is a programmable voltage reference V resulting

in generation of the PWM signal. The voltage reference V

• Fault identification by PGOOD pull down resistance

• Integrated MOSFET drivers with shoot-through protection

• Internal digital soft-start

sets the steady-state PWM frequency. Both rising and falling

edges of the PWM are modulated, providing faster response

to input voltage transients and output load transients than

conventional fixed-frequency PWM controllers. Unlike a

conventional hysteretic converter, the ISL6269 has an error

amplifier that provides ±1% voltage regulation at the FB pin.

• Internal 5V LDO regulator

• Configure forced continuous conduction or diode

emulation for increased light load efficiency

The ISL6269 has a 1.5ms digital soft-start and can be

started into a pre-biased output voltage. A resistor divider is

used to program the output voltage setpoint. The ISL6269

can be configured to operate in forced-continuous-

conduction-mode (FCCM) or in diode-emulation-mode

(DEM), which improves light-load efficiency. In FCCM the

controller always operates as a synchronous rectifier,

switching the low-side MOSFET regardless of the output

load, however with DEM enabled, the low-side MOSFET is

disabled preventing negative current flow from the output

inductor during low load operation. An audio filter prevents

the PWM switching frequency from entering the audible

spectrum due to extremely light load while in DEM.

• PWM minimum frequency above audible spectrum

• Integrated boot-strap diode

• Low-side MOSFET r

DS(ON)

overcurrent protection

• Undervoltage protection

• Soft crowbar overvoltage protection

• Over-temperature protection

• Pb-Free Plus Anneal Available (RoHS Compliant)

Applications

A PGOOD pin indicates when the converter is capable of

supplying regulated voltage. The ISL6269 features a unique

fault-identification capability that can drastically reduce

trouble-shooting time and effort. The pull-down resistance of

the PGOOD pin is 30Ω for an overcurrent fault, 60Ω for an

overvoltage fault, or 90Ω for either an undervoltage fault or

during soft-start. The overcurrent protection is accomplished

• PCI express graphical processing unit

• Auxiliary power rail

• VRM

• Network adapter

by measuring the voltage drop across the r

of the

DS(ON)

low-side MOSFET. A single resistor programs the

overcurrent and short-circuit points. Overvoltage and

undervoltage protection is monitored at the FB voltage

feedback pin.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
