Overview

The NCP346SN1EVB is designed to evaluate and demonstrate several key features of ON Semiconductor’s NCP346SN1 power management IC. This IC is a highly-integrated, single-phase synchronous rectifier designed for AC-DC conversion applications. It integrates all of the active components necessary for a full-bridge AC-DC converter like the NCP346SN1EVB, including a high-side MOSFET, low-side MOSFET, startup, reset, current sense, and thermal protection. The NCP346SN1 is capable of supporting an output power of up to 90W when used with the NCP346SN1EVB.

The NCP346SN1EVB is a cost-effective way for engineers to evaluate the capabilities of ON Semiconductor’s NCP346SN1 IC and also to quickly prototype and develop an AC-DC converter design for power systems. The board ships ready to use, so setup and configuration is fast and easy. The board incorporates several features that make prototyping and evaluating designs with the NCP346SN1 IC faster and easier, such as an integrated voltage divider for current sense, a serial port for programming and monitoring, and an external bootstrap circuit to support high-side and low-side MOSFETs.

Application Field and Working Principle

The NCP346SN1EVB can be used for a wide range of AC-DC conversion applications in the commercial and consumer sectors. It is well-suited for applications such as LED lighting, laptop adapters, telecommunications power supplies, and regulated power supplies. The board is also a valuable tool for designers and application engineers who want to quickly evaluate the performance of the NCP346SN1 IC in their own AC-DC converter designs.

The NCP346SN1EVB takes advantage of the features of the NCP346SN1 IC to provide a highly-integrated, single-phase synchronous rectifier AC-DC converter. The device is a full-bridge circuit with a high-side and low-side MOSFETs for AC-DC conversion, as well as an integrated reset, current sense, start-up, and thermal protection circuitry. To supply power to the IC, an external 12V or 15V DC supply must be connected to the board. The board also includes several connectors that provide access to various signals for analysis, monitoring, and programming.

The NCP346SN1EVB is designed to provide up to 90W of output power and it can support an input voltage in the range of 160VAC to 240VAC. The board is designed with three different output voltage options which include 5V, 12V and 15V. The board also includes several protections to safeguard the IC, such as under-voltage lockout, over-voltage protection, short circuit protection, and thermal shutdown. The board also contains a soft-start feature that ensures the output voltage ramps up slowly and gradually.

The NCP346SN1EVB is controlled by an external microcontroller. The board includes a serial port through which the microcontroller can be used to program the settings of the board or monitor its operating parameters. The microcontroller can also be used to control the output voltage of the board by varying the duty cycle of the high-side and low-side MOSFETs of the bridge.
