General Description

The Supertex HV9110 through HV9113 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.

Because they utilize Supertex’s proprietary BiCMOS/DMOS tech-

nology, they require less than one tenth of the operating power of

conventional bipolar PWM ICs, and 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 voltages between 10

and 120VDC, requiring no external power resistor. The output

stage is push-pull CMOS and thus requires no clamping diodes

for protection, even when significant lead length exists between

the output and the external 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.

For similar ICs intended to operate directly from up to 450VDC

input, please consult the data sheet for the HV9120/9123.
