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
deadtime.
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.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is 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-020B.
