<h3>Introduction</h3><p>PQ1CG2032FZH is a Linear Voltage Regulator IC with a low quiescent current, wide operating voltage range, wide output voltage range and high maximum input voltage. It includes a 3-terminal adjustable regulator, full protection features and a high input current spike rejection rate. This device can be used to regulate the voltage in applications such as POS (Point of Sale) systems and a variety of switching power supplies.</p><h3>Application Field</h3><p>PQ1CG2032FZH is a DC/DC Switching Regulator IC. It is mainly used as a voltage regulator in Point Of Sale (POS) systems and a variety of switching power supplies. It is also used for controlling and monitoring applications such as CNC machines, industrial machinery, medical equipment, etc. The device can also be used for automotive, home appliances and other applications.</p><h3>Working Principle</h3><p>The PQ1CG2032FZH is a DC/DC switching regulator circuit. It contains an integrated, high performance switching regulator controller, a power MOSFET, an oscillator and other related components. The design of the circuit implements a voltage mode control loop, which controls the output voltage of the circuit. As the voltage at the input of the circuit increases, the controller switches the MOSFET on and off at a certain frequency to ensure that the circuit maintains a stable output voltage. When the output voltage is too high, the switching frequency increases; when the output voltage is too low, the switching frequency decreases. The output voltage is adjustable. The regulators provide a low quiescent current, wide operating voltage range, wide output voltage range and high maximum input voltage.</p><h3>Conclusion</h3><p>In summary, PQ1CG2032FZH is a DC/DC Switching Regulator IC featuring low quiescent current, wide operating voltage range, wide output voltage range, high maximum input voltage and full protection features. It is widely used as voltage regulator in Point Of Sale (POS) systems and a variety of switching power supplies, as well as for controlling and monitoring applications such as CNC machines, industrial machinery, medical equipment, automotive, home appliances and other applications.</p>
