Introduction:
The Supertex SR086DB1 is an inductorless switching power
supply intended for operation directly from a 120/230VAC
line. Two outputs, 12.6V and 3.3V are provided.
The operating principle is to turn on a pass transistor when
the rectied AC input is below the output voltage, and to turn
it off when the output storage capacitor is charged up to the
regulation point. Since the output capacitor charges up on
the rising edge of a sine wave, reasonable efciencies can
be obtained without the use of magnetics.
Instructions on page 2 and 3 describe how the demoboard
may be modied to better suit applications that are not satis-
ed by the board as provided. For a full description of the
SR086, see the SR086 datasheet.
Notes:
1. Adjustable from 9.0V to 50V.
2. Referenced to V
OUT.
WARNING!!!
Do not connect earth-grounded loads
or test instruments. Doing so will short
the AC line, resulting in damage to the
instrument, load, and/or the SR086 circuit.
Uese floating instruments or high voltag
differential probes. Do not use a
transformer on the AC line.
WARNING!!!
No galvanic isolation.
Dangerous voltages are
present when connect to
the AC line.
