High-Performance Notebook PWM

Features

Controller with Audio-Frequency Clamp

• High performance R technology

The ISL6269B IC is a Single-Phase Synchronous-Buck

PWM 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 and bootstrap diode result in

fewer components and smaller implementation area.

• Fast transient response

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

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

• Output voltage range: +0.6V to +3.3V

• Wide output load range: 0A to 25A

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

frequency PWM and hysteretic PWM while eliminating many

of their shortcomings. R technology employs an innovative

• Selectable diode emulation mode for increased light load

efficiency

modulator that synthesizes an AC ripple voltage signal V ,

analogous to the output inductor ripple current. The AC signal

• Programmable PWM frequency: 200kHz to 600kHz

• Pre-biased output start-up capability

• Integrated MOSFET drivers and bootstrap diode

• Internal digital soft-start

enters a window comparator where the lower threshold is

the error amplifier output V

, and the upper threshold is a

COMP

programmable voltage reference V resulting in generation

of the PWM signal. The voltage reference V sets the steady-

state PWM frequency. Both edges of the PWM can be

modulated in response to input voltage transients and output

load transients, much faster than conventional fixed-

frequency PWM controllers. Unlike a conventional hysteretic

converter, the ISL6269B has an error amplifier that provides

±1% voltage regulation at the FB pin.

• Power good monitor

• PWM minimum frequency above audible spectrum

• Fault protection

- Undervoltage protection

- Soft crowbar overvoltage protection

- Low-side MOSFET r

overcurrent protection

DS(on)

- Over-temperature protection

The ISL6269B 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 ISL6269B

can be configured to operate in continuous-conduction-

mode (CCM) or diode-emulation-mode (DEM), which

improves light-load efficiency. In CCM the controller always

operates as a synchronous rectifier however, when DEM is

enabled the low-side MOSFET is permitted to stay off,

blocking negative current flow into the low-side MOSFET

from the output inductor.

- Fault identification by PGOOD pull down resistance

• Pb-free plus anneal available (RoHS compliant)

Applications

• PCI express graphical processing unit

• Auxiliary power rail

• VRM

• Network adapter

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are 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.
