New product
Sharp's chopper regulator
PQ1CG2032FZ/PQ1CG2032RZ
of TO-220 package uses PWM method.
It is suitable for the applications of large voltage difference
between input and output and applications of negative power
supply thanks to its low heat loss.
(1) Maximum switching current: 3.5 A
(2) Built-in ON/OFF control function
(3) Built-in soft start function to suppress overshoot of
output voltage in power on sequeuce or ON/OFF
controll sequence.
(4) Built-in oscillation circuit
(Oscillation frequency : TYP. 70 kHz)
(5) Built-in overheat/overcurrent protection function
(6) TO-220 type package
(7) Variable output voltage
(Output variable range : 1.26 to 35 V/-1.26 to -30 V)
[Possible to choose step-down output/inversing output
according to external connection circuit]
