The Supertex HV9100 through HV9103 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.
Utilization of Supertex proprietary BiCMOS/DMOS technology
results in a device with one tenth of the operating power of
conventional bipolar PWM ICs, which 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 voltage between 10
and 70VDC for the HV9100 or 10 to 120VDC for the HV9102 and
HV9103, requiring no external power resistor. The output stage
for the HV9100 is a 150V, 5.0 ohm MOSFET and for the HV9102
and HV9103 is a 200V, 7.0 ohm 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.
