FN6348.0

High-Performance Notebook PWM

Controller

Features

• High performance R technology

The ISL6268 IC is a Single-Phase Synchronous-Buck PWM

controller featuring Intersil's Robust Ripple Regulator (R )

• 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

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.

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 modulator that synthesizes an AC ripple voltage

• Diode emulation mode for increased light load efficiency

• Programmable PWM frequency: 200kHz to 600kHz

• Pre-biased output start-up capability

• Integrated MOSFET drivers and bootstrap diode

• Internal digital soft-start

signal V , analogous to the output inductor ripple current. The

AC 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

• Power good monitor

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 ISL6268 has an error

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

• Fault protection

- Undervoltage protection

- Soft crowbar overvoltage protection

- Low-side MOSFET r

overcurrent protection

DS(on)

- Over-temperature protection

- Fault identification by PGOOD pull-down resistance

The ISL6268 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 ISL6268

normally operates in continuous-conduction-mode (CCM),

automatically entering diode-emulation-mode (DEM) at low

load for optimum efficiency. In CCM the converter operates

as a synchronous rectifier. In DEM the low-side MOSFET

stays off, blocking negative current flow from the output

inductor.

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.
