SC402BMLTRT Integrated Circuits (ICs)

Introduction

The SC402BMLTRT, also known as a Switching and Linear Regulator, is a type of power management integrated circuits (PMIC). These PMICs are designed to regulate the voltage level of a device. It is important to have such a PMIC in any device that needs stabilized power supply. The SC402BMLTRT is an advanced integrated circuit which provides efficient, high power density, and cost effective solutions for power management applications.

Application Field

The application field of the SC402BMLTRT switching and linear regulator includes a wide range of electronic products, ranging from consumer goods, industrial equipment, medical devices, automotive and aerospace to other power electronic applications. By implementing a SC402BMLTRT, manufacturers and designers can achieve high efficiency and performance with a low component count. Its low power and small size allow it to be used in space-constrained applications, such as handheld electronics or embedded systems. Furthermore, its high temperature operating range of 0 ̊C to 85 ̊C makes it suitable for use in high temperature applications.

The SC402BMLTRT is intended for multi-output application, support up to three output channels. One of the outputs is dedicated to a 5V rail and the other two are capable of adjustable output range between 0.89V and 3.6V. It is also capable of delivering up to 60A of continuous output current. Furthermore, it supports various features such as synchronization, phase-inversion, external SYNC and a Power Hiccup Mode (PHM).

Working Principle

The SC402BMLTRT consists of two main parts: the linear regulator and the switching regulator. The Linear Regulator is responsible for providing constant voltage output to the external components. It operates by comparing the input voltage to a reference voltage and automatically adjusting the output voltage to the amount needed. It is capable of providing up to 0.9V to 3.6V of regulation.

The switching regulator provides the bulk of the power to the system. It is a type of DC/DC converter which operates by adjusting the duty cycle of a high-frequency clock. This allows it to provide high current efficiently even at low input voltages. It is capable of delivering up to 60A of continuous current with a maximum output voltage of 5V.

The SC402BMLTRT supports various features including synchronization, phase-inversion and the Power Hiccup Mode (PHM). The synchronization feature allows the user to synchronize the PWM clock with an external clock signal, allowing more precise and efficient power conversion. The phase-inversion feature enables the user to control the input/output phase relationship, allowing for improved system control. The Power Hiccup Mode is an advanced safety feature that automatically shuts down the circuit if it detects an overload or any other abnormal conditions.

Conclusion

The SC402BMLTRT is an advanced power management integrated circuit which is capable of providing efficient, high power density and cost-effective solutions for a wide range of applications. It is capable of providing up to 60A of continuous current with a maximum output voltage of 5V, as well as supporting synchronization, phase-inversion and the Power Hiccup Mode (PHM). These features make it suitable for use in battery-powered, portable, and embedded systems applications.
