MAXM17505EVKIT#

MAXM17505EVKIT evaluation board, an evaluation board specifically designed for the MAXM17505 IC international rectifier, is designed to be used for the evaluation of isolated DC-DC flyback and forward converters. Evaluation boards offer designers an effective way to self-educate, test, and quickly demonstrate solutions in a spreadsheet-free environment.

This MAXM17505EVKIT offers a wide range of applications as a DC-DC or AC-DC converter, including audio amplifiers, battery voltage regulation, mobile phone base stations, and notebook computer adapters. The board features:

• Input Voltage Range: +12V to +19V DC
• Output Voltage Range: +3.3~5V DC, adjustable
• Synchronous Rectification: No
• Switch Frequency: 2.5MHz
• Quiescent Current: <1mA

This evaluation board is capable of operation at elevated temperatures up to +125 degrees Celsius. The main components are an on/off switch, an internal reverse dc-dc converter, a push button control, a power LED indicator, and three different go/no-go LEDs for easy reading. This product also has a very high immunity to electrical interference. This evaluation board requires no minimum input voltage, no EMI/RFI filtering, and reduced external component count for a small and efficient solution for multiple output designs.

The MAXM17505EVKIT# works on a few principles depending on the application. In DC-DC converters, it features synchronous rectification and synchronous rectification control. Synchronous rectification works by replacing the diode with an active low side switch and thus enhancing power conversion efficiency. The rectified diode in the power supply can be replaced by active components that allow higher efficiency at lower load currents.

In AC-DC converters, the MAXM17505EVKIT# has an auto restart capability and PWM control. Auto restart detects a power failure and restarts the output voltage. This eliminates the need for manual restarting and reduces power consumption at idle. PWM control allows the output voltage to be changed depending on load demand, as the output current can be adjusted to the desired level for a given output voltage.

In summary, the MAXM17505EVKIT# application field and working principle can be applied to a wide range of electronic projects, offering adjustable DC and AC-DC converters with synchronous rectification control, auto restart capability, and PWM control. This makes it an ideal product for designers looking for a small, efficient, and reliable power supply.
