Introduction

SP6669EB is a type of evaluation board, and its full name is "DC/DC & AC/DC (Off-Line) SMPS Evaluation Board". This entry-level DC/DC, AC/DC SMPS evaluation board was developed by Shenzhen CPLD Technology Co., Ltd. It is mainly used to test and evaluate the performance of power solutions from leading DC/DC & AC/DC (Off-Line) SMPS suppliers.

Applications

The SP6669EB can be used in a variety of applications that require high performance power solutions such as consumer electronics, computer peripherals, automotive and industrial products. It can also be used for testing and evaluation of LED lighting solutions, battery charging, AC/DC motors and other power and energy management applications. The DC/DC & AC/DC (Off-Line) SMPS evaluation board features a wide range of electrical features such as wide input voltage range, multiple output voltages, wide operating temperature range, over current and over voltage protection, and ripple rejection.

Working Principle

The working principle of the SP6669EB is based on the principle of buck-boost converter topology. It is a switching-mode power supply that operates on the principle of step-down and step-up of an input voltage within the input voltage range. When a DC voltage is applied to the input, the SP6669EB converter adjusts the input voltage by step-down (buck) or step-up (boost) depending on the desired output voltage value. As such, the SP6669EB provides an efficient low heat and low power loss solution for power conversion applications.

The SP6669EB works on pulse-width modulated (PWM) control technology. In PWM, a square wave signal of the desired frequency is applied to a power switch that drives the inductor. The duty cycle of the signal is proportional to the amount of inductor current sent to the output capacitor. As the inductor current varies, the output voltage is maintained at the desired value. When the output voltage drops due to load fluctuations, the PWM control increases the Duty Cycle of the square wave signal and sends more inductor current back to the output capacitor. This maintains the output voltage within its operating range.

Advantages

The SP6669EB has several advantages over other AC/DC SMPS solutions. Firstly, it is a high-efficiency design, with a typical efficiency rating of 90%. Secondly, it has low EMI noise levels, making it suitable for sensitive application with stringent EMI regulations. Thirdly, the power switch and the output capacitor are designed to withstand a wide operating temperature range. Lastly, the SP6669EB has multiple output voltage options, allowing for a flexible voltage adjustment and easy customization for a variety of applications.

Conclusion

The SP6669EB is an ideal DC/DC & AC/DC (Off-Line) SMPS Evaluation Board designed to provide a simple, reliable and cost-effective solution for power conversion requirements in a wide variety of applications. It provides an efficient, low heat and low power loss solution for a wide range of power solutions and is capable of delivering high performance output for a variety of power applications.
