DATASHEET
ISL6740, ISL6741
Flexible Double Ended Voltage and Current Mode PWM Controllers
The
ISL6740, ISL6741
family of adjustable frequency, low
power, Pulse Width Modulating (PWM) voltage mode
(ISL6740) and current mode (ISL6741) controllers, is designed
for a wide range of power conversion applications using
half-bridge, full bridge and push-pull configurations. These
controllers provide an extremely flexible oscillator that allows
precise control of frequency, duty cycle and dead time.
This advanced BiCMOS design features low operating current,
adjustable switching frequency up to 1MHz, adjustable
soft-start, internal and external over-temperature protection,
fault annunciation, and a bidirectional SYNC signal that allows
the oscillator to be locked to paralleled units or to an external
clock for noise sensitive applications.

NOTES:
1. Add “-T” suffix for 2.5k unit tape and reel options. Please refer to
TB347
for details on
reel specifications.
2. 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.
3. For Moisture Sensitivity Level (MSL), please see product information page for
ISL6740,
ISL6741.
For more information on MSL please see techbrief
TB363.
