The EL7566DRE-EVAL is a part of a line of evaluable power supplies manufactured by Intersil. This specific type is classified as an evaluation board for a controllerless, offline DC/DC, AC/DC Switch-Mode Power Supply (SMPS). The EL7566DRE-EVAL is an ideal choice for the design and evaluation of flyback converters for professional and industrial applications.

This particular board has been manufactured specifically for use in the evaluation of the Elantec EL7566 Synchronous PWM Controller. This device consists of a low-side power MOSFET driver, a voltage scale-down feedback comparator, a low-dropout (LDO) linear regulator, a quadrature oscillator, and gate drive circuitry.

The board is designed to evaluate the EL7566 Synchronous PWM Controller in various topologies and in single– and multiple-end flyback converters. Examples include a boost converter, a buck-boost converter, and an SEPIC converters.

The EL7566DRE-EVAL board features a voltage comparator circuit that has been designed for use with the EL7566 PWM Controller. This circuit is able to measure both the voltage drop and current flow in the converter, making it an ideal tool for the evaluation of the device.

The board also comes with the necessary components to evaluate the device in different configurations. These include an adjustable potentiometer and a switching test board, which are both connected to the EL7566 to be tested.

The EL7566DRE-EVAL also features a control circuit, which consists of an integrated MOSFET and serial control. This control circuit is used to adjust the output voltage of the flyback converter under evaluation and to provide a signal to the PWM controller. The control circuit is connected to the EL7566 using a serial bus, allowing fine-tuning of the output. In addition, the control circuit includes an adjustable power supply for further voltage regulation.

In addition to evaluating the EL7566 PWM Controller, the EL7566DRE-EVAL board can be used to evaluate other types of non-controlled SMPSs. Examples include single-stage phase-shift converters, forward converters, and dual-sync buck converters. These converters can be evaluated in order to test the capability of the board to operate in different situations.

The EL7566DRE-EVAL is an ideal board for those needing to evaluate a variety of offline switch-mode power supplies. With its wide range of features and components, the board is perfect for evaluating and optimizing power supplies for various industrial and professional applications.
