PRELIMINARY DATA SHEET
Input Supply Voltage (VIN)................................................................................................................................... -0.3V to 16V
Output Voltage, no load .......................................................................................................... Internally Limited to 1800VRMS
Output Current .......................................................................................................................... 7.5mARMS (Internally Limited)
Output Power (for 2 lamps)..............................................................................................................................................12W
Input Signal Voltage (BRITE , VSYNC Input)...................................................................................................... -0.3V to +6.5V
Input Signal Voltage (SLEEP).................................................................................................................... -0.3V to VIN +0.5V
Ambient Operating Temperature, zero airflow ..................................................................................................... 0°C to 70°C
Storage Temperature Range ............................................................................................................................ -40°C to 85°C
Note 1: Exceeding these ratings could cause damage to the device. All voltages are with respect to Ground. Currents are positive into, negative out of
specified terminal.
This module has been designed to operate over a wide range of input and output conditions. However, best efficiency and performance will be obtained if
the module is operated under the condition listed in the ‘R.C.’ Column. Min. and Max. columns indicate values beyond which the inverter, although
operational, will not function optimally.
