Demonstration circuit 2268A-F is a high efficiency, high density, dual 8A, switch mode step-down power supply on a compact 1.5' × 1.2' PCB. It features the LTM4630A μModule® regulator. The input voltage is from 4.5V to 15V. The output voltage is programmable from 0.6V to 5.3V. DC2268A-F can deliver up to 18A maximum in each channel. As explained in the data sheet, output current derating is necessary for certain VIN, VOUT, and thermal conditions. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the resistor jumper (R1/R2) selects pulse-skipping mode for noise sensitive applications or Burst-Mode® in less noise sensitive applications. Two outputs can be connected in parallel for a single 36A output solution with optional jumper resistors. The board allows the user to program how its output ramps up and down through the TRACK/SS pin. Remote output voltage sensing is available for improved output voltage regulation at the load point. An optional input inductor L1 reduces the EMI noise for noise sensitive applications. DC2268A can be easily inserted to an edge connector for testing and debugging. These features and the availability of the LTM4630A in a compact 16mm × 16mm × 4.41mm LGA package make it ideal for use in many high-density point-of-load regulation applications. The LTM4630A data sheet must be read in conjunction with this demo manual for working on or modifying the DC2268A-F.

The LTC5597 is a high accuracy RMS power detector that provides a very wide RF input bandwidth, from 100MHz up to 70GHz. This makes the device suitable for a wide range of RF and microwave applications, such as point-to-point microwave links, instrumentation and power control applications. The DC output voltage of the detector is an accurate representation of the average signal power applied to the RF input. The response is linear-in-dB with 28.5mV/dB logarithmic slope over a 35dB dynamic range with typically better than ?1dB accuracy. The detector is particularly suited for measurement of waveforms with crest factor (CF) as high as 12dB, and waveforms that exhibit a significant variation of the crest factor during measurement. To achieve higher accuracy and lower output ripple, the averaging bandwidth can be externally adjusted by a capacitor connected between the FLTR and OUT pins.
