Other Parts Discussed in Thread: TPS92640
Hi,
I am comparing TPS92515HV and TPS92640. I dont understand the main reason of different dimming ratio between those 2 parts.
Also, I didnt find out what is the recommended Shunt PWM frequency operation. Is it depend on which FET that I chose? If so, can you give me an example of best case scenario.
| Parts | Amps | Voltage Range | Shunt PWM | PWM | Analog |
| TPS92515HV | 2A | 5.5V - 65 V | 10000:1 | 1000:1 | 200:1 |
| TPS92640 | 1A | 7V - 85V | 20000:1 | 2500:1 | 500:1 |
Thanks,
