Flexible Single-ended Current Mode PWM
Controller
The ISL6721A is a low power, single-ended pulse width
modulating (PWM) current mode controller designed for a
wide range of DC/DC conversion applications including
boost, flyback, and isolated output configurations. Peak
current mode control effectively handles power transients
and provides inherent overcurrent protection. Other features
include a low power mode where the supply current drops to
less than 200μA during overvoltage and overcurrent
shutdown faults. It differs from the ISL6721 in that the UVLO
and UV thresholds have been modified.
This advanced BiCMOS design features low operating
current, adjustable operating frequency up to 1MHz,
adjustable soft-start, and a bidirectional SYNC signal that
allows the oscillator to be locked to an external clock for
noise sensitive applications.
