Chopper Regulators
PQ1CZ1
I
ON/OFF Control Terminal
In the following circuit,when ON/OFF control terminal
t
becomes low by switching transistor Tr on, output voltage may
be turned OFF and the device becomes stand-by mode. Dissipation current at stand-by mode becomes Max.400
μ
A.
<Soft start>
When capacitor Cs is attached, output pulse gradually expanded and output voltage will start softly.
<ON/OFF control with soft startup>
For ON/OFF control with capacitor C
S
, be careful not to destroy a transistor Tr by discharge current from C
S
, adding a
resistor restricting discharge current of C
S
.
