High-Performance Notebook PWM

Controller with Bias Regulator and

Audio-Frequency Clamp

Features

• High performance R technology

• Fast transient response

• +0.6V Internal Reference

The ISL6269 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, 5V LDO and bootstrap diode result in

fewer components and smaller implementation area.

- ±0.6% tolerance over the commercial temperature

range (0°C to +70°C)

- ±1.0% tolerance over the industrial temperature range

(-40°C to +85°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

modulator that synthesizes an AC ripple voltage signal V ,

analogous to the output inductor ripple current. The AC signal

• Selectable diode emulation mode for increased light load

efficiency

enters a window comparator where the lower threshold is

• Programmable PWM frequency: 200kHz to 600kHz

• Pre-biased output start-up capability

• Internal 5V LDO for self-biasing

the error amplifier output V

programmable voltage reference V resulting in generation

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

, and the upper threshold is a

COMP

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 ISL6269 has an error amplifier that provides ±1% voltage

regulation at the FB pin.

• Integrated MOSFET drivers and bootstrap diode

• Internal digital soft-start

• Power good monitor

• PWM minimum frequency above audible spectrum

• Fault protection

- Undervoltage protection

- Soft crowbar overvoltage protection

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 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.

- Low-side MOSFET r

overcurrent protection

- Over-temperature protection

- Fault identification by PGOOD pull-down resistance

NOTE: 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.

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