DMD43153F
Specifications and Applications
Information
11/09/07
Preliminary
The ERG DMD43153F (DMD Series) DC to AC inverter
features onboard connectors and can be easily dimmed
using the onboard PWM Dimming or an external PWM
generator.
Powered by a regulated +12 Volt DC source, the
DMD43153F is designed to power the backlight of the
Optrex T-51863D150J-FW-A-AB/AD and AA150XN02
displays.

(Note 1) Input current in excess of maximum may indicate a load/inverter mismatch condition, which can result in
reduced reliability. Please contact ERG technical support.
(Note 2) Surface temperature must not exceed 80 degrees C; thermal management actions may be required.
(Note 3) Provided data is not tested but guaranteed by design.
Application Notes:
1) The minimum distance from high voltage areas of the inverter to any conductive material should be .12
inches per kilovolt of starting voltage.
2) Mounting hardware to be non-conductive.
3) Open framed inverters should not be used in applications at altitudes over 10,000 feet.
4) Contact ERG for possible exceptions.

Pin Descriptions
+Vin
Input voltage to the inverter. The two pins should be connected for optimum reliability and efficiency.
GND
Control
Enable
Inverter ground. The four pins should be connected for optimum reliability and efficiency.
Analog voltage input to the onboard pulse width modulator. Decreasing this voltage increases the ON
time of the onboard PWM resulting in increased brightness. The inverter is full ON when this voltage is
near inverter ground.
Inverter Enable. Pull this pin low to disable inverter operation. This pin must be high to enable the
inverter. The onboard PWM is always utilized.
Application information
The DMD series of inverters is designed to power up to four cold cathode fluorescent lamps. An external analog
control interfaces with an onboard pulse width modulator to provide dimming control. The DMD inverter can reliably
dim to less than 5% duty cycle.
External shutdown of the inverter is accomplished using the Enable pin. Pulling this pin low (below Vthoff) disables
the inverter. Enabling the inverter is accomplished by pulling this pin high (above Vthon).
If analog voltage dimming is required, the analog voltage is applied to the Control pin. Figure 1 shows how to
connect the inverter for onboard PWM operation. Graph 1 shows the relationship of PWM duty cycle to input control
voltage.
If an external PWM is used, connect the Enable pin to the PWM source and connect the Control pin to inverter
Ground. If the onboard PWM is used, connect the analog voltage to the Control pin.
