Other Parts Discussed in Thread: LMC8101, TINA-TI, LM321
I am looking for a low cost linear single-LED driver for the following requirements:
- Vin: 3.5V-8V
- LED Vf: 3.2V
- Iled: 40mA-300mA - resistor programmable
- Iled accuracy: +/-5%
- As low cost and small as possible but no BGA/CSP packages
Do you have a recommended circuit for this? Would the TS321 be the best fit? I tried the below on Tina which seems to work fine (PNs are just for illustration - I used different devices and adjusted parameters), but want to make sure I'm not missing anything. Any low-cost way to generate the 200mV reference (or a smaller/lower cost LM10-type device)?
