Demonstration circuit 1126 is a high density dual output (3.3V/5A and 2.5V/5A) step down converter featuring the LTC3850EUF. The input voltage range is 6.5V to 14V. For applications that have a 5V +/- 0.5V input, the board has an optional resistor to tie the INTVCC pin to the VIN pin. An optional DCR sense circuit 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 to improve efficiency.

Demonstration circuit 1128A is a dual channel synchronous, 2.25MHz Step-Down DC/DC Regulator featuring the LTC3419. The DC1128A has an input voltage range of 2.5V to 5.5V. Both jumper selectable 3.3V/2.5V and 1.2V/1.5V/1.8V outputs are capable of delivering up to 600mA of output current. The device also features independent internal soft-start for each channel.

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.

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.

The LT5579 mixer is a high performance upconverting mixer optimized for frequencies in the 1.5GHz to 3.8GHz range. The single-ended LO input and RF output ports simplify board layout and reduce system cost. The mixer needs only ?1dBm of LO power and the balanced design results in low LO signal leakage to the RF output. At 2.6GHz operation, the LT5579 provides high conversion gain of 1.3dB, high OIP3 of +26dBm and a low noise floor of ?157.5dBm/Hz at a ?5dBm RF output signal level. The LT5579 offers a high performance alternative to passive mixers. Unlike passive mixers, which have conversion loss and require high LO drive levels, the LT5579 delivers conversion gain at significantly lower LO input levels and is less sensitive to LO power level variations. The lower LO drive level requirements, combined with the excellent LO leakage performance, translate into lower LO signal contamination of the output signal.Applications GSM/EDGE, W-CDMA, UMTS, LTE and TD-SCDMA Basestations 2.6GHz and 3.5GHz WiMAX Basestations 2.4GHz ISM Band Transmitters High Performance Transmitters
