HV9112  
High-Voltage Current-Mode PWM Controller  
General Description  
Features  
► 10V to 120V Input Voltage Range  
► Current-mode control  
► High efficiency  
► Up to 1.0MHz internal oscillator  
► Internal start-up circuit  
► Low internal noise  
The Supertex HV9112 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 HV9112 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.  
Applications  
► DC/DC converters  
► Distributed power systems  
► ISDN equipment  
► PBX systems  
► Modems  
Accessory functions are included to permit fast remote shutdown  
(latching or nonlatching) and under voltage shutdown.  
Ordering Information  
For similar ICs intended to operate directly from up to 450VDC  
input, please consult the data sheets for the HV9120 and  
HV9123.
