General Description

The Supertex HV9100 through HV9103 are a series of BiCMOS/

DMOS single-output, pulse width modulator ICs intended for use

in high-speed high-efficiency switchmode power supplies. They

provide all the functions necessary to implement a single-switch

current-mode PWM, in any topology, with a minimum of external

parts.

Utilization of Supertex proprietary BiCMOS/DMOS technology

results in a device with one tenth of the operating power of

conventional bipolar PWM ICs, which can operate at more than

twice their switching frequency. Dynamic range for regulation is

also increased, to approximately 8 times that of similar bipolar

parts. They start directly from any DC input voltage between 10

and 70VDC for the HV9100 or 10 to 120VDC for the HV9102 and

HV9103, requiring no external power resistor. The output stage

for the HV9100 is a 150V, 5.0 ohm MOSFET and for the HV9102

and HV9103 is a 200V, 7.0 ohm MOSFET. The clock frequency

is set with a single external resistor.

Accessory functions are included to permit fast remote shutdown

(latching or nonlatching), and undervoltage shutdown.
