Features

General Description

BiCMOS/DMOS technology

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.

Current mode control

49% duty cycle operation

Programmable START/STOP capability

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

+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.

15V to 250V input range internal start-up regulator

6.0µA standby supply current for +V_IN<20V

0.9mA operating supply current

5.0V V_DDsupply operation

30KHz to 300KHz internal oscillator

15KHz to 150KHz converter output frequency

1.0MHz low offset error amplifier

1.20V 2% band gap reference

Output driver optimized for under 10W applications

Low driver output impedance with V_DD= 0V

Fast (90nsec) over current shutdown

All pins are ESD protected
