Product Details

Demonstration circuit 2177A-B features the LT3062, a micropower, low noise and low dropout voltage linear regulator. The input voltage ranges from 2.1V to 45V and the maximum output current is 200mA. A resistor divider determines the output voltage, and a jumper adjusts the divider to set the output voltage to either 1.2V, 1.5V, 1.8V, 2V, 2.5V, 3.3V, 5V or a voltage that is user-programmed but requires the installation of a resistor. The output uses a 10μF ceramic capacitor and the internal reference is bypassed with a 10nF capacitor to reduce output noise and program the soft-start. There is also a 10nF feedforward capacitor to improve load transient response and decrease noise at higher output voltages. The position of the VOUTEN jumper either pulls up the SHDN pin to the input supply through a 100k resistor, shorts SHDN to ground or floats the SHDN pin so it can be driven directly by a signal applied to the SHDN terminal.

Features and Benefits

  • Analog Devices has worked closely with Intel PSG to develop verified power solutions that optimize cost, size and efficiency in high performance applications.
  • The validated power solutions include uModules power products that address time and space constraints while delivering high efficiency, reliability, and low noise.
  • The actual power tree represents the best solution at time of design.
  • A recommended power tree has also been included to present the ideal solution at time of Stratix 10 GX PCIe development kit release. An updated alternate version of the power tree represents the latest solutions available from Analog Devices. For many applications, an intermediate rail is not ideal, so recommendations an alternate power tree that allow for direct power conversion from 12V input is provided below.
