REG711EA-3/2K5

Reg711EA-3/2K5 is a DC-DC switching regulator controlled by switch power supply. It belongs to the category of PMIC (Power Management ICs) - Voltage Regulators - DC DC Switching Regulators. This type of regulator is usually used to deliver an output voltage that is different from the input voltage and features adjustable output voltage, high accuracy and low noise.

The most common application of Reg711EA-3/2K5 is in desktop computers and laptops where the regulator controls the switching power supply to deliver different output voltages from the input voltage. Reg711EA-3/2K5 also has a wide range of applications in consumer electronics, automotive, medical, industrial, and other power management solutions.

The working principle of the Reg711EA-3/2K5 is based on a pulse-width modulation (PWM) operation. The feedback voltage is taken from the output to compare with the reference voltage, normally from a voltage divider. This comparison is used to modulate the drive signal of the power switching transistor, which then produces the output voltage.

When the comparison is made, the pulse is width modulated. When the feedback voltage is higher than the reference voltage, the pulse width is decreased. This decreases the amount of power sent to the load, thereby decreasing the output voltage. Conversely, if the feedback voltage is lower than the reference voltage, the pulse width is increased. This increases the power sent to the load, and the output voltage is increased.

Reg711EA-3/2K5 also has a built-in soft-start feature that reduces inrush current and generates a low voltage across the output capacitor as it starts up. With it, the Reg711EA-3/2K5 also has a high output current capability up to 2.5A.

To guarantee the stability of the Reg711EA-3/2K5, an external compensation network needs to be used. This network consists of an inductor, a capacitor and an optional resistor. The inductor limits the high frequency current spikes, and the capacitor filters out the low frequency noise from the output voltage.

Reg711EA-3/2K5 is a valuable regulator in a variety of applications. Its adjustable output voltage, high accuracy, low noise and fast response characteristics make this regulator an ideal choice for providing steady and reliable power supplies.
