High-Performance Notebook PWM

Controller

Features

• High performance R technology

The ISL6269A 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

• Programmable PWM frequency: 200kHz to 600kHz

• Pre-biased output start-up capability

• Integrated MOSFET drivers and bootstrap diode

• Internal digital soft-start

signal V enters a window 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

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

• Power good monitor

• Fault protection

- Undervoltage protection

- Soft crowbar overvoltage protection

conventional hysteretic converter, the ISL6269A has an error

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

- Low-side MOSFET r

overcurrent protection

DS(on)

- Over-temperature protection

The ISL6269A 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 ISL6269A

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

Applications

• PCI express graphical processing unit

• Auxiliary power rail

• VRM

• Network adapter
