DC1819A: Demo Board for the LTC4415 Dual 4A Ideal Diodes with Adjustable Current Limit,

DC1836A-B: Demo Board for the LTC2955 Pushbutton On/Off Controller with Automatic Turn-On.

The LTC6947 is a high performance, low noise, 6GHz phase-locked loop (PLL), including a reference divider, phase-frequency detector (PFD), ultralow noise charge pump, fractional feedback divider, and VCO output divider.The fractional divider uses an advanced, 4th order ?? modulator which provides exceptionally low spurious levels. This allows wide loop bandwidths, producing extremely low integrated phase noise values.The programmable VCO output divider, with a range of 1 through 6, extends the output frequency range. The differential, low-noise output buffer has user-programmable output power ranging from ?4.3dBm to +4.5dBm, and may be muted through either a digital input pin or software.The ultralow noise charge pump contains selectable high and low voltage clamps useful for VCO monitoring, and also may be set to provide a V+/2 bias.All device settings are controlled through a SPI-compatible serial port.Applications Wireless Basestations (LTE, WiMAX, W-CDMA, PCS) Broadband Wireless Access Microwave Data Links Military and Secure Radio Test and Measurement

DC1851A: Demo Board for the LTC2872 RS232/RS485 Dual Multiprotocol Transceiver with Integrated Termination.

Demonstration circuit 1901A is a 150V input, 100mA output DC/DC power supply featuring the LTC3639. The IC operates in a high efficiency Burst Mode® operation and includes internal high and low side power MOSFETs. The board will accept an input voltage between 4V and 150V, and provide jumper selected output voltages of 1.8V, 3.3V, 5V and an option for additional voltages. The IC includes internal soft-start and a provision for increasing soft-start time.

The LTC3129 is a high efficiency, 200mA buck-boost DC/DC converter with a wide VIN and VOUT range. It includes an accurate RUN pin threshold to allow predictable regulator turn-on and a maximum power point control (MPPC) capability that ensures maximum power extraction from non-ideal power sources such as photovoltaic panels.The LTC3129 employs an ultralow noise, 1.2MHz PWM switching architecture that minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. Built-in loop compensation and soft-start simplify the design. For high efficiency operation at light loads, automatic Burst Mode operation can be selected, reducing the quiescent current to just 1.3?A.Additional features include a power good output, less than 10nA of shutdown current and thermal shutdown.The LTC3129 is available in thermally enhanced 3mm ? 3mm QFN and 16-lead MSOP packages. For fixed output voltage options, see the functionally equivalent LTC3129-1, which eliminates the need for an external feedback divider.
