This application field is specifically designed for efficient power delivery for critical and general-purpose applications. It provides high-efficiency, cost-competitive solutions for a broad range of commercial, industrial and automotive end-use products.

The S-8351A30MC-J2PT2G is very efficient, featuring a wide input voltage range from 4.5V to 24V, while upgrading the regulation accuracy to 1%. It also offers a high output current at a maximum of 1.5A and a temperature range of -40 to 85 °C. It allows step down (buck converter) or step up (boost converter) conversion with lower EMI and is designed to include a built-in soft start feature.

Working Principle

The S-8351A30MC-J2PT2G DC/DC switching regulator works with voltage step-down (buck converter) and step up (boost converter) conversion to provide efficient power delivery for a variety of applications including commercial, industrial and automotive. It utilizes a control PWM (pulse width modulation) which applies voltage reduction or voltage boost in order to regulate the output voltage according to the input voltage. This is achieved by providing a feedback signal to the comparator level when the output voltage goes below a certain level. This feedback signal triggers the conversion of voltage from high to low or from low to high and the comparator level sets the amount of voltage conversion.

The S-8351A30MC-J2PT2G also employs a built-in soft start feature that prevents the uncontrolled startup current and limits the inrush current at start up. This helps to impedance inrush current that can damage the circuitry of the switch regulator. The soft start feature uses a time delay mechanism to limit the current in order to control the current output over time.

Conclusion

The S-8351A30MC-J2PT2G DC/DC switching regulator from Seiko is a great choice for efficient power delivery for a variety of applications. It provides a wide input voltage range from 4.5V to 24V and a high output current with a maximum of 1.5A. It also has a built-in soft start feature that helps to control inrush current and improve protection of the circuitry. This is an effective and efficient solution for commercial, industrial and automotive end-use applications.
