The default EVM configuration has a single device and the external components populated, however, an additional device can be populated. This allows testing for two different dual-device applications:
- Redundant - Each device has a different VIN source but a common VOUT. The common VOUT is already implemented on the EVM through a shared plane. In this configuration, each device has a separate external components.
- Parallel - Each device has the same VIN source as well as a common VOUT. To connect the VIN for both devices, populate the 4 parallel size 2512, 1-W, 0-Ω resistors (R8, R9, R10 and R11). The EN, OVP, CS, SS, RTIMER and ILTIMER pin nodes of the devices must sepalso be connected by populating 0-Ω resistors (R19, R21, R23, R20, R22 and R24 respectively). The external components for U2, except for the IL pin, are also typically removed for parallel operation.
