General 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 imple-
ment 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

. The output stage is push-pull CMOS,
eliminating the need for external clamping diodes. The clock
frequency is set with a single external resistor.
