产品详情

Demonstration circuit 1433 is an adjustable 5A linear regulator featuring the LT3070. The LT3070 is a low dropout voltage, UltraFast™ transient response linear regulator. The device supplies up to 5A of output current with a typical dropout voltage of 85mV. A 0.01μF reference bypass capacitor decreases output voltage noise to 25μVRMS. The LT3070’s high bandwidth permits the use of low ESR ceramic capacitors. Output voltage is digitally selectable in 50mV increments over a 0.8V to 1.8V range. The demo board has a 1.2V to 3V input voltage range and a 2.5V to 3.6V BIAS voltage range. A margining function allows the user to tolerance system output voltage in increments of ±1%, ±3% or ±5%. To maintain proper performance and regulation, the BIAS supply voltage must be higher than the IN supply voltage. For a given VOUT, the BIAS voltage must satisfy the following conditions: 2.2 ≤ VBIAS ≤ 3.6V and VBIAS ≥ (1.25 · VOUT + 1V).


For VOUT ≤ 0.95V, the minimum bias voltage is limited to 2.2V.

特性和优点

The HTG-937 provides access to large FPGA gate density and 8GB/16GB of high bandwidth memory. It is populated with the Xilinx Zynq Virtex Ultrascale VU37P, or VU47P. Analog Devices power solution on this platform is fully validated to meet the requirements of Xilinx Zynq Virtex Ultrascale FPGAs to ensure a robust power delivery solution.

DC/DC μModule regulators are used on the HTG-937 to power Xilinx FPGA and/or SoC rails as well as other system rails. These regulators are highly integrated solutions with built in controller, power FETs, inductors, and capacitors that simplify layout and provide robust power delivery performance.

We provide supporting documentation including power schematics, layout, LTpowerPlanner and applicable LTpowerPlay configuration files to enable you to validate the power solution for your application seamlessly.
