Products Detail

The PQ1CG21H series is a TO-220 type chopper regulator that uses PWM method. It features maximum switching current of 1.5A, built-in ON/OFF control function, soft start function to suppress output voltage overshoot, oscillation circuit (100 kHz typical), and overheat/overcurrent protection. The device offers variable output voltage ranging from 1.26 to 35V for step-down output or -1.26 to -30V for inverting output depending on external circuit connection. Available in two forming types: zigzag (PQ1CG21H2FZ) and self-stand (PQ1CG21H2RZ).
