Synchronizing Current Mode PWM for
Subscriber Line Interface Circuits (SLICs)
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.
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 55 μ A in
the shutdown mode.

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.
