Tool/software:
Hi Sir,
My customer design their TPS61289 board already and its function is ok currently. Bt duel to their high environment (40C) temperature requirement, TPS61289is 108C at their chamber test. Anything they can modify to improvie the heat performance at their board?
1. D39/D40/D41/D42 are NC
2. Input 20.5V / Output:22.07V
3. Output current: 4.6A
4l U1 is 66C at room temperature (25C)
Thanks and regards,
Gary Teng
