The DC901A evaluation board is a synthesized dual-channel switching power supply with high power density, wide input voltage range, high efficiency, and powerful EMI suppression capability. It is an ideal choice for portable products such as test instruments, communications equipment, and consumer electronic products.

The DC901A evaluation board is suitable for multiple switching power supply designs, including DC/DC, AC/DC (off-line) SMPS, and boost control. The evaluation board adopts a multi-level topology architecture and uses integrated power device to achieve higher power density and wider output voltage range.

The basic schematic diagram of the DC901A evaluation board is as shown below. It consists of an input filter, a rectifier, and a full bridge converter. The input filter, integrated in the evaluation board, consists of a line filter (1-2, 4-5) and an EMI filter (3-7, 8-9). It can effectively suppress the EMI problem caused by the input power supply.

The rectifier of the evaluation board uses boost rectification technology. It can obtain higher output voltage than the input voltage and make up for the voltage drop caused by the line filter. And the full bridge converter is composed of synchronous rectifier FETs (MOSFETs). Its main feature is the wide input voltage range, which is suitable for high voltage applications.

The DC901A evaluation board is equipped with a wide range of protections. The output voltage is monitored by a voltage feedback circuit, which can detect Operation Abnormal and Over Current then drive the MOSFETS to shut down. It also has an integrated over temperature protection, which will force the MOSFETs to shut down when the internal temperature exceeds a certain threshold. Besides, the DC901A evaluation board is able to support remote control shutdown.

One of the most impressive features of the DC901A evaluation board is its excellent performance. It has a high power density of 1.2 kW/in³ and a wide operating temperature range of -40°C to +85°C. The maximum efficiency of the board is up to 92%. And it can reduce EMI by up to 50dBc. The evaluation board also has a low power standby mode, which can reduce the power consumption and improve the overall efficiency of the power supply.

In conclusion, the DC901A evaluation board is a powerful, efficient, and reliable power supply solution for a variety of applications. It can achieve higher power density, wider input voltage range, and better EMI suppression capability. With its wide range of features, the DC901A evaluation board is an ideal choice for power supply designs.
