General Description
The Supertex HV9105 and HV9108 are high-efficiency high
voltage SMPS ICs intended for use in power converters requiring
extreme efficiency at output power levels of 5.0W or less. The low
supply current (0.5mA max) allows them to be used to build
supplies which meet CCITT I.430 performance recommenda-
tions (60% efficiency at .025W out).
The HV9105/08 provides all the functions necessary to build a
single-switch current-mode converter of any common topology,
with a minimum of external parts.
In addition to high efficiency, because it uses Supertex’s propri-
etary high voltage BiCMOS/DMOS technology, the HV9105/08
offers numerous performance advantages when compared to
conventional PWM ICs. Dynamic range is approximately 8 times
wider than with bipolar ICs, both response speed and maximum
clock rate are faster, and no external power resistors or zeners are
necessary for high voltage starting.
Accessory circuits are included to provide either latching or
nonlatching shutdown. When shut down, device dissipation is
less than 4mW.
The HV9105/08 is intended for operation with input voltages from
10 to 120VDC.
