3.1 Schematics

The following figure shows the LMH13000RQEEVM schematic diagram.

Note:

  1. C2 and R22 by default is populated in AMPS251B (previous revision of EVM, Rev.B) EVM. In the latest revision (AMPS251C) they are made DNI. If using AMPS251B, remove C2 to avoid any instability in the IOUT waveform. Also, R22 is short in AMPS251B EVM, remove it to operate the EVM in LVDS input mode
  2. The RC snubber networks (R1–C4 and R25–C32), along with the damping resistor R21, may be adjusted by the user to optimize performance based on the required output current (IOUT) and desired transient response characteristics. By default, the components value are set as follows: R1 = R25 = 5 Ω, C4 = C32 = 300 pF, and R21 = 2 Ω.
