PMIC (Power Management Integrated Circuits) have become the go-to solution for managing power in a wide range of applications. Voltage regulators are one type of PMIC, and the EL5126CL-T7 is a special purpose voltage regulator. These products provide an efficient way of regulating the voltage in a target application, making them highly valuable for many uses. In this article, we\'ll explore the EL5126CL-T7\'s application field and its working principle.

EL5126CL-T7 Application Field

The EL5126CL-T7 is suitable for use in various scenarios. This voltage regulator is ideal for applications that require a precise voltage regulation. It is designed to operate as low as 3.3V, meaning it can be used in low power devices. This part is also suitable for applications where the power is technically on 24/7 and in need of a regulated voltage. This voltage regulator can also be used in high temperature environment such as automotive and industrial applications. The EL5126CL-T7 has a wide temperature range of -40 to 85 C.

This voltage regulator has a high power-efficiency rate. It is capable of providing up to 50mA output current at 3.3V output voltage with a low quiescent current of 2.5mA for space-sensitive applications. It features a wide voltage supply range of 2.7V to 7V. This ensures the device can handle the input voltage range of very low supply voltage from 2.7V to 7V, providing a great deal of flexibility for system power supply design.

The EL5126CL-T7 features an adjustable voltages. With a low noise and ripple voltage, it provides an excellent output voltage accuracy within 0.2%. Additionally, the output over-voltage protection (OVP) prevents output voltage from exceeding the design value when there is an overload condition at the input voltage.

EL5126CL-T7 Working Principle

The EL5126CL-T7 works by regulating the input voltage, which is usually AC, to an output voltage. For example, if the input voltage is 5V and the output voltage is 3.3V, the voltage regulator will reduce the input voltage to 3.3V and output it as a regulated voltage. This is done by controlling the amount of current that is allowed to pass through the regulator.

The EL5126CL-T7 uses a simple but highly efficient non-synchronous buck topology to regulate the output voltage. The buck topology involves a two-stage process, in which an inductor is utilized to store energy from the input voltage. This energy is then released, allowing the regulator to reduce the input voltage and output a regulated, steady output voltage.

The EL5126CL-T7 also uses a PWM (pulse width modulation) control scheme. The PWM control scheme modulates the width of the pulses applied to the gate of the power switches, allowing it to continuously adjust the duty cycle and regulate the output voltage.

This voltage regulator also has various onboard protection mechanisms designed to protect the system against various overload conditions. These protection mechanisms include over current protection (OCP), over temperature protection (OTP), and over voltage protection (OVP).

Conclusion

In summary, the EL5126CL-T7 is a highly efficient voltage regulator that is suitable for low power, high temperature, and space-sensitive applications. It features a wide voltage supply range, adjustable output voltage, over-voltage protection, and a high power-efficiency rate. It also uses a non-synchronous buck topology and PWM control scheme to regulate the output voltage, making it an ideal choice for a range of application fields.
