Synchronizing Current Mode PWM for

Subscriber Line Interface Circuits (SLICs)

Features

• Positive and Negative Output Regulation

The ISL6401 adjustable frequency, low power, pulse width

modulating (PWM) current mode controller is designed for a

wide range of DC/DC conversion applications including

boost, flyback, and isolated output configurations. The

device is optimized to provide a high performance, low-cost

solution for Ringing SLIC (RSLIC) ring and talk power

supplies. An integrated inverter allows for easy design of

negative voltage regulation circuits with a minimal amount of

external components. Internal soft-start minimizes start-up

stress without any external components. Peak current mode

control effectively handles Ring trip transients and provides

inherent overcurrent protection.

• Starting Supply Current . . . . . . . . . . . . . . . . . 100µA (typ.)

• Quiescent Current . . . . . . . . . . . . . . . . . . . . . . 55µA (typ.)

• Output Frequency Range. . . . . . . . . . . . 50kHz to 600kHz

• External Clock Synchronization

• Fast Transient Response with Peak Current Mode Control

• Internal Soft-Start

• Drives N-Channel MOSFET

• Logic Level Shutdown

• Leading Edge Blanking

This advanced BiCMOS design features low operating

current, adjustable operating output frequency (50kHz to

600kHz), internal soft-start and a SYNC input that allows the

oscillator to be locked to an external clock for noise sensitive

applications. DC/DC conversion efficiency is optimized by

use of a low current sense voltage. A logic level shutdown

input is included, which reduces supply current to 55µA in

the shutdown mode.

• 1% Tolerance Voltage Reference Over Line and

Temperature

• Pb-Free Available (RoHS Compliant)

2. Intersil Pb-free 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.

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