General Description

The Supertex HV9605C is a BiCMOS/DMOS single-output,

current mode, pulse width modulator IC designed to meet the

requirements of ETR-080 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,

it 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. It 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

eliminating the need for external clamping diodes. The clock

frequency is set with a single external resistor.
