Description

The Supertex HV9605 is a BiCMOS/DMOS single-output, current mode, pulse width modulator IC designed to meet the requirements of ETR-060 for ISDN applications. In a 14 pin package, it provides all the necessary functions to implement a single-switch PWM with a minimum of external parts.

Utilizing Supertex's proprietary BiCMOS/DMOS technology, HV9605 requires less than one tenth of the operating power of conventional bipolar PWM ICs. Dynamic range for regulation is also increased to approximately 8 times that of similar bipolar parts. HV9605 operates directly from any DC input voltage between 15 and 250 VDC. The START and STOP input voltage thresholds can be programmed within the operating input voltage range by means of a resistor divider, provided +V IN(START) > +V IN(STOP). The output stage is push-pull CMOS, eliminating the need for external clamping diodes. The clock frequency is set with a single external resistor.
