User Manual
The ISL6722A and ISL6723A are low power, single-ended pulse width modulating (PWM) current mode controllers designed for a wide range of DC/DC conversion applications including boost, flyback, and isolated output configurations. They offer adjustable operating frequency, adjustable soft-start, and other features.
User Manual
ISL6722A and ISL6723A are low power, single-ended pulse-width modulation (PWM) current mode controllers suitable for a wide variety of DC/DC conversion applications including step-up regulators, buck regulators, and isolated output configurations. Similar to the ISL6721 and pin-compatible, ISL6722A and ISL6723A offer a modified feature set. ISL6722A replaces the original external synchronization function with a low-power halt feature that can reduce standby current below 200µA. ISL6723A changes the input voltage undervoltage threshold to 13V. In addition, internal overtemperature protection has been eliminated for both controllers. The remainder of the controller’s functionality is unchanged and includes a low-power mode that includes current limit and overvoltage fault protection when the input current is below 200µA. An internal 300ms delay clock prevents rapid “hiccups” in the controller’s operation when a fault occurs.
