Advanced PWM and Linear Power

Controller for Portable Applications

Features

• Provides Two Regulated Voltages

The ISL6226 provides power control and protection for two

user selected output voltages required in high-performance

notebook PC applications. The IC integrates a fixed,

selectable frequency pulse-width-modulation (PWM)

controller and a 3A LDO linear regulator controller with

monitoring and protection circuitry in a single 24 lead SSOP

package.

- Linear Regulator, User Selected, Current Limited

- High Efficiency PWM Over Wide Line and Load Range

- Synchronous Buck Converter on PWM Output

- Hysteretic Operation at Light Load

• Dual Mode Operation:

- Directly From Battery Input, V , of 5.6V to 24V or from

The PWM controller regulates the battery input voltage to a

user selected output voltage. Synchronous converter and

hysteretic operation at light loads contribute to a high

efficiency over a wide range of input voltage and load

variation. Efficiency can be further enhanced by using the

of 5V

• PWM Output Adjustable From 0.9V to 0.93*V

• Low Drop-Out (LDO) Linear Regulator Operates from

Vout+0.5V to 24V

lower MOSFET’s r

as the current sense element. Input

• LDO Output Adjustable

DS(ON)

voltage feed-forward ramp modulation, current-mode control,

and internal feed-back compensation provide fast and stable

handling of input voltage load transients encountered in

advanced portable computer chip sets.

- From 0.8V to 3.8V at 0A to 3A for NPN Transistor

- From 0.8V to 3.0V at 0A to 3A for N-MOSFET

• 300/600kHz Switching Frequency Selectable

• Forced PWM Mode Control Option

• No Current-Sense Resistor Required on PWM Output

The internal linear regulator controller provides a user

selected high current output from an unregulated input with

user selected current limit.

- Uses MOSFET’s r

DS(ON)

- Optional Current-Sense Resistor for More Precision
