OPERATIONAL DESCRIPTION (Continued)
C
L
High Speed Discharge
XC9235B(C)/ XC9236B(C)/ XC9237B(C) series can quickly discharge the electric charge at the output capacitor (C
L
) 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
X
pin and the V
SS
pin. When the IC is disabled, electric charge at the output capacitor (C
L
) is quickly
discharged so that it may avoid application malfunction. Discharge time of the output capacitor (C
L
) is set by the C
L
auto-discharge resistance (R) and the output capacitor (C
L
). By setting time constant of a C
L
auto-discharge resistance
value [R] and an output capacitor value (C
L
) as
(
=C x R), discharge time of the output voltage after discharge via the N
channel transistor is calculated by the following formulas.
