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 components. Internal soft start minimizes start-up stress without any external components. Peak current mode control effectively handles Ring trip transients and provides inherent over-current protection.
This advanced BiCMOS design features low operating current, adjustable operating output frequency (50kHz to 600kHz), internal soft-start and a SYNC input that allows the oscillator to be locked to an external clock for noise sensitive applications. DC-DC conversion efficiency is optimized by use of a low current sense voltage. A logic level shutdown input is included, which reduces supply current to 55uA in the shutdown mode.
