Supertex, Inc. introduces the HV9605C, a high voltage current mode PWM controller IC, used mainly in low power telecommunication applications. Its logic input supply voltage is 5V and its operating current is 1.3mA maximum. It meets the requirements of ETR-080 for ISDN applications. The IC's unique Start-Stop function eliminates oscillations caused by the voltage drop due to high telephone line resistance in long loops.
