The UC3844, UC3845 series are high performance fixed frequency
current mode controllers. They are specifically designed for Off Line and DC to
DC converter applications offering the designer a cost
effective solution with minimal external components. These integrated
circuits feature an oscillator, a te
mperature compensated reference, high
gain error amplifier, current sens
ing comparator, and a high current
totem pole output ideally suited for driving a power MOSFET.

Operating Instructions
1 Two bit digital tube display area, the corresponding screen reference list through the digital tube below the add and subtract key to display the number of 01-55,. LCD screen line power supply short circuit, the digital tube does not stop flashing display “00”, while the buzzer.
2 The power button (red hat), press the power button, LCD screen and power supply, voltage indicating exhibit of lanterns lit. The power button up the LCD screen, disconnect
the power supply. So, in the test, the replacement of the LCD screen just press the power button to.
3 Screen voltage switch, according to different sizes of LCD screen, to select the appropriate screen power supply voltage, 3.3V/5V/12V
optional. Long press the button for 5 seconds, the voltage will
automatically jump at the same time, the corresponding voltage
indicator lights exhibit of lanterns
4 The backlight interface, defined as the standard general high voltage
board / 6pin board interface, is used for the external LCD screen of the
high pressure plate / boost plate.
Backlight interface, the definition of 6pin is a standard for the
general high voltage board / boost board interface for external LCD
screen with high pressure plate / boost plate, for some small size LCD
backlight for 5V, can also be used for our future development of various
expansion board power supply
5 Â LVDS output port, the foot is defined as the standard definition of
the market on the ordinary driver board / common screen line, can be
directly bought the screen line to use.
6 Screen switch button for the 12 standard test screen cycle switch.
7 Quality switch keys, the built-in test screen without a full screen, the
effect is not HERSHEY’S, can be used to switch to the appropriate
picture.
8 Â Automatically switch keys, press a button, the built-in test screen will
automatically show, at this time the digital tube two decimal point will
be displayed, for the factory assembly, repair and use of the machine.
Press the button again, the automatic cycle is shown to be closed.
9 Â VGA output, for the 12 test images through the VGA signal output,
can be a test instrument when the VGA signal source, to test other
displays.
10 Â VGA output, when inserted into the external computer VGA signal,
the tester automatically switch to the external VGA signal, do not need
to manually switch. Pull back to the built in test chart display.
