A. When Driver is enable we measured below voltage and current…
Part Number: TPS61169 Dear Teams,
My customer is using TPS61169 and select on inductor. Could you help check whether this inductor is appropriate?
Output: 20Vout; 20mA
Inductor datasheet show in the attachment.
Part Number: TPS61169 Customer is driving TPS61169 CTRL pin with PWM with 3.3V MCU. TPS61169 Vin is 3V. This is potentially violating the CTRL maximum absolute maximum.
What do you think, is this a concern?
Part Number: TPS61169 Customer is using TPS61169 to drive 3 series LEDs with 3.2V +/-0.3V Vf, 45 mA If. Measured efficiency is 75%.
Vin = 3.3V Cin 10 uF Cout = 1.0 uF L = 22 uH (LBR2012T220K)
Questions: Does 75% efficiency seems reasonable for this design…
