General Description
The Supertex HV9110 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 HV9110 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.

... A single external resistor between the OSC IN and OSC OUT is required to set the oscillator frequency (see graph). One major difference exists between the Supertex HV9110 and competitive 9110s. On the Supertex part, the oscillator is shut off when a shutoff command is received. This saves about 150µA of quiescent current, which aids in the construction of power supplies that meet CCITT specifi ...
