Vinが 40 V未満のLEDドライバ・ツール
| How does the LED forward voltage Vf compare with the input voltage range? |
More Information
Vf (min) > Vin (max); Step-Up or Boost configuration.
Vf (max) < Vin (min); Step-Down or Buck configuration.
Vf and Vin overlap; SEPIC or Buck-Boost configuration.
|
| What is the required output current? |
| Is your design powered by a low voltage battery (ex. 1 Li-Ion cell)? |
More Information
As a guideline, select Yes when Vin < 5.5 V; otherwise, select No.
