Flexible Double Ended Voltage and Current Mode PWM
Controllers
ISL6740, ISL6741
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.
