All voltages are with respect to Ground. Currents are positive into, negative out of specified terminal. RECOMMEND E D O P ERATING CONDITIONS (R.C.) 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. Recommended Operating Conditions Parameter Symbol Min R.C. Max Units Input Supply Voltage Range (Fully Regulated Lamp Current) 3 3.3 3.6 Input Supply Voltage Range (Functional) VIN1 2.9 4.2 V Output Power PO 2.2 W Linear BRITE Control Input Voltage Range¹ VBRT_ADJ 0.65 to 0.9 2.0 V Lamp Operating Voltage VLAMP 325 380 435* VRMS Lamp Current (Full Brightness) IOLAMP 3.5 5 † mARMS Operating Ambient Temperature Range TA -20 70 °C ¹The minimum VBRT ADJ voltage depends on the panel characteristics, depending on the panel it can vary from 0.65V to 0.9V *Total output power must not exceed 2.2W . Higher voltage lamps may require maximum output current to be set lower than 5mARMS †At voltages below 3.6V the inverter may not be able to output the full 5mARMS in all configurations. ELECTRICAL CHA RACTERISTICS Unless otherwise specified, the following specifications apply over the recommended operating condition and ambient temperature of 25 °C except where otherwise noted.
