HV9906DB2
Off-Line Current Source Controller
Introduction
The Supertex HV9906DB2 demo board contains all
circuitry necessary to demonstrate the features of the
HV9906 second order power supply controller. The
power converter of the demo board consists of an
input buck-boost stage and an output buck stage.
The output voltage polarity is negative. Due to its
unique quadratic input-to-output DC voltage transfer
ratio, the converter can operate directly off AC line to
produce low-voltage output without need for
electrolytic capacitors. HV9906 is designed for
optimal controlling this type of power converter or
other types of two-stage multi-converters.
The board is optimized for driving a 6V 400mA
(700mA max.) LED. However, it may be modified to
meet custom requirements.

Board Layout and Connections
WARNING!!!
Do not connect to scope ground or to the ground of other earth-grounded instruments. Doing so will short the AC line,
resulting in damage to the circuit and/or instruments. Either use an isolation transformer on the AC line, use a
differential probe, or use a floating, battery-powered instrument to make measurements.
WARNING!!!
No galvanic isolation. Dangerous voltages are present when connected to the AC mains.
