TYPICAL APPLICATION CIRCUIT

XCL201/XCL202 Series

●External Components

CIN : 10V/4.7μF(Ceramic)

CL : 6.3V/10μF(Ceramic)

NOTE:

The Inductor can be used only for this DC/DC converter.

Please do not use this inductor for the other reasons.

Please use B, X5R, and X7R grades in temperature characteristics for CIN and CL capacitors.

These grade ceramic capacitors minimize capacitance-loss as a function of voltage stress.
