The MAX1630/MAX1631/MAX1632 evaluation kits (EV kits) each consist of one of three preassembled and tested evaluation boards (EV boards) that embody the standard application circuits. The MAX1630 and MAX1632 EV boards provide the triple-output 3.3V/5V/12V circuit, and the MAX1631 EV board provides the dual-output 3.3V/5V circuit.
All three use the same PC board but have different components to accommodate different input voltage ranges. The main differences between the MAX1630 and MAX1632 EV boards are in the turns ratio (1:4 or 1:2.2) and in the location of the transformer connection (3.3V side or 5V side). Connecting the transformer to the 3.3V side allows lower input voltage. Connecting the transformer to the 5V side provides slightly better efficiency and lower stress voltages.
These circuits are configured to deliver up to 3A of output current on each of the main PWM outputs with greater than 90% efficiency. The MAX1630/MAX1631/MAX1632 EV kits can also be used to evaluate other output voltages.

The MAX1968 evaluation kit (EV kit) is a fully assembled and tested PC board that implements a switch-mode driver for a Peltier thermoelectric cooler (TEC) module. It operates from a single 3.0V to 5.5V supply and provides a bipolar ±3A (max) output to the module.
A potentiometer, DAC, or external source generates a DC temperature set-point voltage. Thermal feedback from the TEC module is compared to the set-point voltage to generate the TEC current-control signal. The MAX1968 accurately regulates the TEC current based on this signal.
When using the DAC, the EV kit connects to the parallel port of a computer running Windows® 95, 98, or 2000. Software, included with the EV kit, provides a quick and easy method to control the DAC.
Note: Windows 2000 requires the installation of a driver. Refer to Win2000.pdf or Win2000.txt located on the diskette.

The MAX274 and MAX275 are continuous-time active filters consisting of independent cascadable 2nd-order sections. Each section can implement any all-pole bandpass or lowpass filter response, such as Butterworth, Bessel, Chebyshev, and is programmed by four external resistors. The MAX274/MAX275 provide lower noise that switched-capacitor filters, as well as superior dynamic performance—both due to the continuous-time design. Since continuous-time filters do not require a clock, aliased and clock noise are eliminated with the MAX274/MAX275.
The MAX274 comprises of four 2nd-order sections, permitting 8th-order filters to be realized. Center frequencies range up to 150kHZ, and are accurate to within ±1% over the full operating temperature range. Total harmonic distortion (THD) is typically better than -86dB.
The MAX275 comprises of two 2nd-order sections, permitting 4th-order filters to be realized. Center frequencies range up to 300kHZ, and are accurate to within ±0.9% over the full operating temperature range. Total harmonic distortion (THD) is typically better than -86dB.
Both filters operate from a single +5V supply or from dual ±5V supplies.

The MAX5940B evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board featuring an Ethernet port, network powered device (PD) interface controller circuit for -48V supply systems. The EV kit uses the MAX5940B IEEE® 802.3af-compliant network PD interface controller in an 8-pin SO package. The MAX5940B EV kit can also evaluate the MAX5940D rated for an absolute maximum input voltage of 90V. The MAX5940B features an internal isolation switch that limits inrush current. The MAX5940B is used in power-over-LAN applications requiring DC power from an Ethernet network port for PDs such as IP phones, wireless access nodes, and security cameras.
The MAX5940B EV kit receives power from an IEEE 802.3af-compliant power sourcing equipment (PSE). See the MAX5922 and MAX5935 data sheets for PSE controllers. The PSE provides the required -44V to -57V DC power over an unshielded twisted-pair Ethernet network cable to the EV kit's RJ-45 jack. The EV kit features a 10/100BASE-TX Voice-over-IP (VoIP) magnetic module and two diode bridges for separating the DC power provided by an endspan or midspan Ethernet system.
The EV kit demonstrates the full functionality of the MAX5940B such as the PD detection signature, configurable PD classification signature, programmable inrush current, and undervoltage lockout (UVLO). All of these features are configurable on the EV kit and additional test points for voltage probing and interfacing have been provided for the PD interface.
The MAX5940B EV kit also features a galvanically isolated 6W, 275kHz switching frequency flyback DC-DC converter, which uses the MAX5014 current-mode PWM controller. The MAX5940B's -48V output provides power for the converter circuit. The DC-DC converter is configured for an output voltage of 4.25V and provides up to 1.4A at the output. High efficiency up to 82.2% is achieved using a single transistor flyback DC-DC converter topology. The surface-mount transformer provides 1500V galvanic isolation for the output. UVLO, soft-start, and thermal shutdown provide a robust 6W isolated power supply.
The EV kit can be reconfigured for interfacing to an external DC-DC converter for an additional 7W of output power.
