DC1133A-A: Demo Board for the LTC2242-12 12-Bit, 250Msps ADC.

DC1147A-E: Demo Board for the LTC6403-1 200MHz, Low Noise, Low Power Fully Differential Input/Output Amplifier/Driver

Demonstration circuit DC1154 is a Telecom non isolated DC/DC converter featuring the LTC3873 constant frequency current mode flyback controller. The DC1154 converts 36V to 72V input voltage to an isolated 3A of output current at 3.3V. The 200kHz constant frequency operation is maintained down to very light load to reduce low frequency noise generated over a wide range of load current. The DC1154 also provides an isolated design by installing the optocoupler and LTC4430 related circuitry. The demonstration circuit can be easily modified to generate different output voltages up to 15V. As output voltage is increased, the maximum output current must be reduced to limit the output power to no more than 10W.

DC1159A: Demo Board for LTC3565 1.25A, 4MHz, Synchronous Step-Down DC/DC Converter

Demonstration circuit DC1177 is a micropower dual Buck-Boost/Buck synchronous converter based on the LTC3522 monolithic regulator. The DC1177 has an input voltage range of 2.4V to 4.2V and outputs 3.3V @ 300mA and 1.8V @ 200mA.

DC1204A: Demo Board for LTC4358 5A Ideal Diode.

DC1226A: Demo Board for the LTC3529 1.5A, 1.5MHz Step-Up DC/DC Converter in 2mm × 3mm DFN

Demonstration circuit 1231A is a Dual Output, Dual Phase 5A Synchronous Buck Converter featuring the LTC3850EGN. The entire circuit, including the bulk output capacitors, fit within a 1.04” × 0.94” area on all layers. The package style for the LTC3850EGN is a 28-lead narrow plastic SSOP. The main features of the board include rail tracking, an internal 5V linear regulator for bias, RUN pins for each output and a PGOOD signal and a Mode selector that allow the converter to run in CCM, pulse skip or Burst Mode operation. Synchronization to an external clock is also possible through some minor component changes. Two versions of the board are available. DC-1231A-A has an on-board sense resistor for current feedback, while the DC1231A-B is configured with a DCR sense circuit that allows the converter to use the inductor’s DCR as the sense element instead of the on-board sense resistors to save cost and board space and improves efficiency.
