I have a customer who has the following LED driver specs
VIn = 41V-45V
Vout = 38V
Iout = 350mA to 1.3A
He wants PWM dimming and needs high side current sense.
Ideally it would be a sub $1 part
Do you have any suggestions?
Cheers
Calum

Calum,
The TPS54160 has been used in LED applications like this. It does not have high side current sensing, but it will support the wide VIN range and current requirements. The softstart pin can be used for PWM control.
Best regards,
