Demonstration circuit DC970A-A and DC970A-B feature the LTC3541 and LTC3541-1 respectfully, and provide a high efficiency, synchronous buck plus VLDO linear regulator. For the LTC3541, the buck regulator powers up before the linear regular, and for the LTC3541-1, the linear regulator powers up first. The DC970A has an input voltage range of 3.0V to 5.5V. The jumper selectable (2.5V or 1.8V) buck regulator output is capable of delivering up to 500mA of output current; the jumper selectable (0.8V, 1.2V, 1.5V or 1.8V) linear regulator output is capable of delivering up to 300mA of current.

The LT3482 is a fixed frequency current mode step-up DC/DC converter with voltage doubler designed to bias avalanche photodiodes (APDs) in optical receivers. It can provide up to 90V output. The LT3482 features high side APD bias current monitoring with better than 10% relative accuracy over the entire temperature range. The integrated power switch, Schottky diodes and APD bias current monitor allow a small converter footprint and low solution cost. Constant switching frequency results in predictable output noise that is easy to filter. The inductor-based topology ensures an input free from switching noise. An integrated high side current monitor produces a current proportional to APD bias current with better than 10% relative accuracy over four decades of dynamic range in the input range of 250nA to 2.5mA. This APD bias current can be used as a reference to provide a digitally programmed output voltage via the CTRL pin. The LT3482 is available in the tiny footprint (3mm ? 3mm) 16-lead QFN package.Applications APD Bias PIN Diode Bias Optical Receivers and Modules Fiber Optic Network Equipment

DC991A: Demo Board for the LT5560 0.01MHz to 4GHz Low Power Active Mixer.

Demonstration circuit 992 is a Step-Down Converter, using the LTC3549 monolithic synchronous buck regulator. The DC992A has an input voltage range of 1.6V to 5.5V, and is  capable of delivering up to 250 mA of output current at a minimum input voltage of 1.8V. The output voltage of the DC992A can be set as low as 0.611V, the reference voltage of the LTC3549. At low load currents, the DC992A can operate in either noise sensitive applications, due to the capability of the LTC3549 to operate in pulse-skipping mode, or in high  efficiency applications, because the LTC3549 can also operate in Burst-Mode.
