DLPS240A June 2024 – August 2024 DLPA3085
PRODUCTION DATA
The DLPA3085 has five drive outputs for the respective five power FETs. The signal swing at these outputs is about 5V. Thus FETs should be selected that are turned on adequately with a gate-source voltage of 5V. For the three LED selection outputs (CHx_GATE_CTRL) and the low-side drive (ILLUM_LSIDE_DRIVE), the drive signal is ground referred. For the ILLUM_HSIDE_DRIVE output, the signal swing is referred to the switch node of the converter, ILLUM_A_SW. All five power FETs should be N-type.
