Hi team,
Do we have automotive LED driver can meet spec:
1. Vin: 7~10V(come from PoC)
2. Vout will connect 2 string IR LED (Vf: 6V, drive current: 2A)
3. PWM dimming, PWM dimming frequency 33.33ms(30Hz), on time 2ms, off time 31.33ms
I have found LP8868-Q1 and tps92643-Q1. LP8868-Q1 can't meet PWM dimming frequency 33.33ms(30Hz), on time 2ms, off time 31.33ms and tps92643-Q1 only has buck topology can't boost voltage from Vin 7~10V to 2 string IR LED 12V. do you have any recommendation for this situation? thanks.
BR,
Jimmy
