Inductor Selection

The LM36010 is designed to use a 0.47-µH or 1-µH inductor. Table 3 lists various inductors and their manufacturers that work well with the LM36010. When the device is boosting (VOUT > VIN) the inductor is typically the largest area of efficiency loss in the circuit. Therefore, choosing an inductor with the lowest possible series resistance is important. Additionally, the saturation rating of the inductor must be greater than the maximum operating peak current of the LM36010. This prevents excess efficiency loss that can occur with inductors that operate in saturation. For proper inductor operation and circuit performance, ensure that the inductor saturation and the peak current limit setting of the LM36010 are greater than IPEAK in Equation 6:

where

  • ƒSW = 2 or 4 MHz

Efficiency details can be found in the Application Curves.
