EVB_RT2101AGQW

The EVB-RT2101AGQW is an evaluation board designed to do rapid prototyping and evaluation of Linear Technology’s RT2101AGQW isolated DC/DC and AC/DC switching mode power supply (SMPS). Specifically, the EVB-RT2101AGQW is an isolated power supply with a wide range of input/output voltage combinations and adjustable output power. The EVB-RT2101AGQW is equipped with a strong selection of features to provide the user with efficient power conversion and protection. Its uses include allowing an engineer to quickly and accurately determine the parameters required to design a reliable system. In addition, the EVB-RT2101AGQW allows the testing of various SMPS topologies and components, and serves as a cost effective alternative to the development of a custom printed circuit board.

The EVB-RT2101AGQW evaluation board consists primarily of a switching power supply packaging area, input and output connectors, and a DC-DC controller chip. The RT2101AGQW is an adjustable, integrated, isolated SMPS controller for flyback converters. Its key parameters include a wide input voltage range (85-265V AC), wide output voltage range (2-45V/1-30V DC), and a wide adjustable output power range (90-125w). The EVB evaluates the internal features of the RT2101AGQW such as resonant mode operation (RMO) for improved efficiency, true RMS current mode control for improved transient performance, and an integrated soft-start feature with an active reset circuit for increased performance.

The RT2101AGQW controller is integrated into the switching power supply package with standard components. The system board consists of an output filter, EMI filter, input and output capacitors, and a driver stage. The RT2101AGQW contains a feedback loop and output voltage adjustment circuitry. The integrated soft-start feature prevents output voltage from overshooting, while the active reset circuit helps to ensure that all parameters remain stable and tightly regulated during operation. The EVB-RT2101AGQW is packaged in a 1.6” x 2.4” board allowing it greater flexibility for testing SMPS designs in various levels of complexity. The RT2101AGQW can also be used as a controller for an external power supply, and the EVB-RT2101AGQW serves as a great platform for that purpose as well.

The EVB-RT2101AGQW is designed to offer reliable power conversion with simple, fast setup and evaluation. It is a powerful tool for rapid prototyping and evaluation of linear technology’s RT2101AGQW isolated DC/DC and AC/DC switching mode power supplies. The RT2101AGQW integrated controller provides a wide range of features and options for both adjustable and non-adjustable power supplies. The wide range of input/output voltage combinations and adjustable output power range make the EVB-RT2101AGQW an excellent solution for many different applications.
