Demonstration circuit 1590B is a dual output synchronous buck converter featuring the LTC3880EUJ, a dual output peak current mode controller with digital power system management. There are two versions of the board available: DC1590B-A senses the output current across a sense resistor and has a default switching frequency of 350kHz, and DC1590B-B senses output current with the inductor DCR and has a default switching frequency of 425kHz. Either version can be populated with the LTC3880EUJ-1 (which allows the user to provide bias power to the IC from an external power supply) instead of the LTC3880EUJ. These boards provide two programmable outputs of 20A each. The factory default settings are 1.8V for each output.

The LTC3607 is a 15V dual 600mA monolithic synchronous step-down regulator which has only 55?A quiescent current. Intended for a variety of applications, including dual lithium-ion battery products, it operates from a wide 4.5V to 15V input voltage range. It features a constant 2.25MHz switching frequency, enabling the use of tiny, low cost capacitors and inductors 1mm or less in height. Each output voltage is adjustable from 0.6V to VIN. The internal synchronous power switches provide high efficiency without the need for external Schottky diodes.A user selectable mode input is provided to allow the user to trade off ripple noise for light load efficiency; Burst Mode operation provides the highest efficiency at light loads, while pulse-skipping mode provides the lowest ripple noise.To further the maximize battery run time, the P-channel MOSFETs are turned on continuously in dropout (100% duty cycle). In shutdown, the device draws <1?A.Applications Dual Lithium-Ion Battery Supplies Automotive Applications Servers

The HMC601LP4(E) Logarithmic Detector/Controller converts RF signals at its input, to a proportional DC voltage at its output. The HMC601LP4(E) employ a successive compression topology which delivers extremely high dynamic range and conversion accuracy over a wide input frequency range. As the input power is increased, successive amplifiers move into saturation one by one creating an accurate approximation of the logarithm function.The output of a series of square law detectors is summed, converted into voltage domain and buffered to drive the LOGOUT output. For detection mode, the LOGOUT pin is shorted to the VSET input, and will provide a nominal logarithmic slope of 19mV/dB and an intercept of -100 dBm. The HMC601LP4(E) can also be used in the controller mode where an external voltage is applied to the VSET pin, to create an AGC or APC feedback loop. The HMC601LP4(E) provides a 15/34ns (rise/fall time) response time enabling RF burst detection to a pulse rate beyond 20 MHz.Applications Cellular/PCS/3G WiMAX, WiBro & Fixed Wireless Power Monitoring & Control Circuitry Receiver Signal Strength Indication (RSSI) Automatic Gain & Power Control Circuits
