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 +VIN(START) > +VIN(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.
Applications
❏ ISDN network terminations
❏ ISDN terminals
❏ ISDN terminal adapters
❏ Feature phones
❏ SLIC circuits
❏ PBX systems
❏ Modems
❏ Distributed power systems
❏ DC/DC converters
