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.
