The DC2517A evaluation board is designed as an off-line Switch Mode Power Supply (SMPS) and is used in a variety of applications ratings from 10W to 30W. The evaluation board comes equipped with two isolated Switch Mode Power Supply (SMPS) outputs and adjustable frequencies of up to 400kHz. This makes it well suited to a range of applications, from embedded systems to consumer electronics and industrial applications.

The form factor for the DC2517A is fairly compact; the board measures only 2” x 2”. This makes it easy to install and allows the use of it in most applications easily. The board is also well suited for use in harsh or hazardous environments due to it’s robust design and well protected components.

The DC2517A operates in an off-line, two stage flyback topology. It consists of a main power switch (MOSFET) connected to an input 45-265 VAC power source. An AP7535 Flyback controller governs the operation of the power stage. The controller adjusts the average MOSFET on time based on the voltage feedback from the energy storage inductor. This adjusts the output voltage and provides overcurrent protection.

The DC2517A is supplied with two isolated outputs, rated at up to 15W each. The board also includes adjustable frequency and overcurrent protection, allowing the output to be adjusted for maximum efficiency. The switch frequency is adjustable from 30kHz to 400kHz, allowing the design of compact and efficient power stages.

The DC2517A’s two outputs can be configured for buck, boost, or flyback operation. The board also includes features such as undervoltage lockout (UVLO) and overload protection, which provides an additional layer of protection for the device. The DC2517A is also well suited for use in Industrial, Telecom, and Consumer applications as it is designed to operate under harsh conditions and withstand long periods of continuous operation.

The DC2517A is a great tool for designers looking to rapidly evaluate and develop their product. Featuring an adjustable frequency and outputs, the DC2517A is well suited for a range of applications from embedded devices to industrial machines. With it’s robust design and compact form factor it is an ideal choice for engineers looking for an efficient off-line SMPS solution.
