The E1402 (E200IIE200IIE200IIE200IIE200II SeriesSeriesSeriesSeriesSeries) dc to ac
inverter is specifically designed to power
the Seiko G242CX LCD display backlight
to a moderate brightness level from a +12
Volt dc source.
E200II Package
The E1402's small size, encapsulated
package and low input power requirements
(typically 1.2 Watts) make it the ideal power

Specifications subject to change without notice.
(Note 1) Surface temperature must not exceed 80 degrees C; thermal management actions may be required.
(Note 2) 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 3) Provided data is not tested but guaranteed by design.
Application Notes:
1) Printed circuit boards to be free of traces beneath the inverter.
2) The minimum distance from high voltage areas of the inverter to any conductive material should be .12
inches per kilovolt of starting voltage.
3) ACreturn should be left floating, not grounded.
4) Contact ERG for possible exceptions.
Endicott Research Group, Inc. (ERG) reserves the right to make changes in circuit design and/
or specifications at any time without notice. Accordingly, the reader is cautioned to verify that

data sheets are current before placing orders. Information furnished by ERG is believed to be
accurate and reliable. However, no responsibility is assumed by ERG for its use.
