The MAX17536EVKITA# evaluation board is an AC/DC (off-line) switch mode power supply (SMPS) specifically designed for the evaluation of the MAX17536 converter IC. It is the ideal tool for engineers looking to understand and evaluate the features and benefits of the IC and evaluate various applications. The board is capable of providing an adjustable voltage ranging from 0V to 8V with a maximum output current of 1.5A. It is suitable for applications such as LED drivers, battery chargers, portable device power supplies, embedded-distributed power systems, and automotive power systems.

The MAX17536EVKITA# evaluation board is designed as a complete AC/DC SMPS powered by an input voltage ranging from 85-130VAC or 180-265VAC. It consists of the MAX17536 IC, two MAX8814A ICs, a PFC pre-regulator, a PWM controller, and a power switch. The entire circuit is housed in a standard 6 layered PCB design.

The PFC pre-regulator is an active power factor correction circuit that helps to reduce the power loss from the AC line. This pre-regulator takes advantage of the MAX17536’s wide input voltage range and allows it to produce a regulated output voltage while maintaining high efficiency. It also helps to ensure that the output voltage remains constant regardless of the input voltage.

The PWM controller is an integrated circuit designed to regulate the output voltage. It takes a control voltage input and uses a combination of the reference voltage and the feedback voltage to generate an output signal. This output signal is used by the power switch to control the switchable output voltage. The integrated quantity controller or PFC pre-regulator can be used to adjust the output voltage level. This allows for easy implementation of various applications and powers levels.

The integrated power switch is used to switch between the various output levels and is normally controlled by the PWM controller. For the MAX17536EVKITA# evaluation, board, a Fairchild FDC641N is used for switching operations. The FDC641N features a low on-resistance of <2 ohms, allowing it to achieve high efficiency. The board also features reverse polarity protection, allowing the converter to protect itself from sudden voltage spikes or in-rush current.

The MAX17536 is a highly efficient offline SWIFFT-based flyback converter, making it a perfect solution for high power applications. The MAX17536 boasts high efficiency at low load, making it an ideal choice for LED drivers or battery chargers. Additionally, its wide input voltage range, from 85 200VAC, ensures compatibility with a wide variety of applications. The converter also features a digital constant current control, allowing for precise current regulation, rapid response time, and easy implementation.

In summary, the MAX17536EVKITA# evaluation board is the ideal solution for engineers looking to evaluate the features and benefits of the MAX17536 offline SWIFFT-based flyback converter IC. It combines a PFC pre-regulator, PWM controllers, a power switch, and the MAX17536 IC, all in a compact, standard 6 layered PCB design. The board provides the highest efficiency and features reverse polarity protection, allowing it to protect against in-rush currents or voltage spikes. It works with a wide range of input voltages and can be used to evaluate various applications, such as LED drivers, battery chargers, portable device power supplies, embedded-distributed power systems, and automotive power systems.
