■OPERATIONAL DESCRIPTION (Continued)
＜C
The XCL205B(C,G)/ XCL206B(C,G)/ XCL207B(C,G) series can quickly discharge the electric charge at the output capacitor (C
when a low signal to the CE pin which enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor
located between the L
discharged so that it may avoid application malfunction. Discharge time of the output capacitor (C
auto-discharge resistance (R) and the output capacitor (C
and an output capacitor value (C
transistor is calculated by the following formula.
