TPS61165: SUITABLE LED DRIVER FOR 40 HZ FREQUENCY

SYED ALI NAJEEM

Part Number: TPS61165

Hi,

I need a suitable LED driver to drive 8 LEDS (350 mA/2V) at 40 Hz. Please suggest to me a suitable LED driver. The main control parameter is PWM (40 HZ).

Hi,

Should the LED current also be PWM wave? And could you please provide the Vin as well?

The current may be PWM. However, we only need to toggle LEDs at 40 Hz (for spcl purposes).

The supply voltage is 12 V. However we can change them based on requirement if needed

Hi,

For now we have no suitable device could support 40Hz PWM frequency.
