Overview: DATASHEET ISL6401
Synchronizing Current Mode PWM for Subscriber Line Interface Circuits (SLICs) FN9007 Rev 8.00 Oct 21, 2015 The ISL6401 adjustable frequency, low power, pulse width modulating (PWM) current mode controller is designed for a wide range of DC/DC conversion applications including boost, flyback, and isolated output configurations. The device is optimized to provide a high performance, low-cost solution for Ringing SLIC (RSLIC) ring and talk power supplies. An integrated inverter allows for easy design of negative voltage regulation circuits with a minimal amount of external ponents. Internal soft-start minimizes start-up stress without any external ponents. Peak current mode control effectively handles Ring trip transients and provides inherent overcurrent protection.
