General Description

The Supertex HV9113 is a BiCMOS/DMOS single-output,

pulse width modulator IC intended for use in high-speed,

high-efficiency switch mode power supplies. It provides all the

functions necessary to implement a single-switch current mode

PWM, in any topology, with a minimum of external parts.

Because the HV9113 utilizes Supertex’s proprietary BiCMOS/

DMOS technology, it requires less than one tenth of the operating

power of conventional bipolar PWM ICs, and can operate at

more than twice their switching frequency. The dynamic range

for regulation is also increased, to approximately 8 times that

of similar bipolar parts. It starts directly from any DC input

voltage 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 under voltage shutdown.

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

input, please consult the data sheets for the HV9120 and

HV9123.

For detailed circuit and application information, please refer to

application notes AN-H13 and AN-H21 to AN-H24.
