ISL9440, ISL9440A, ISL9441

Triple, 180° Out-of-Phase, Step-Down PWM and Single Linear Controller

FN6383

Rev 2.00

February 9, 2015

The ISL9440, ISL9440A and ISL9441 are quad-output

synchronous buck controllers that integrate 3 PWM

Features

• Three integrated synchronous buck PWM controllers

- Internal bootstrap diodes

controllers and 1 low drop-out linear regulator controller, which

are full featured and designed to provide multi-rail power for

use in products such as cable and satellite set-top boxes,

VoIP gateways, cable modems, and other home connectivity

products as well as a variety of industrial and general purpose

applications. Each output is adjustable down to 0.8V. The

PWMs are synchronized at 180° out of phase thus reducing

the RMS input current and ripple voltage.

- Internal compensation

- Internal soft-start

• Independent control for each regulator and programmable

output voltages; independent enable/shutdown

• Fixed Switching Frequency: 300kHz (ISL9440, ISL9441);

600kHz (ISL9440A)

The ISL9440, ISL9440A and ISL9441 offer internal soft-start,

independent enable inputs for ease of supply rail

• Adaptive shoot through protection on all synchronous

buck controllers

sequencing, and integrated UV/OV/OC/OT protections in a

space conscious 5mmx5mm QFN package. The ISL9440

and ISL9440A offers an early warning function to output a

logic signal to warn the system to back up data when the

input voltage falls below a certain level.

• Independently programmable voltage outputs

• Out-of-phase switching to reduce input capacitance

(0°/180°/0°)

• No external current sense resistor

- Uses lower MOSFET’s r_DS(ON)

The ISL9440, ISL9440A and ISL9441 are utilize internal loop

compensation to keep minimum peripheral components for

compact design and a low total solution cost. These devices

are implemented with current mode control with feed forward

to cover various applications even with fixed internal

compensations.

• Current mode controller with voltage feed forward

• Complete protection

- Overcurrent, overvoltage, undervoltage lockout,

over-temperature

• Cycle-by-cycle current limiting

The table below shows the difference in terms of the

ISL9440, ISL9440A and ISL9441 features.

• Wide input voltage range

- Input rail powers VIN Pin: 5.6V to 24V
