2.1.2 Modification

The EVM is designed to support some modifications by the user. The external components like input caps, output caps, feedback resistors, and so forth can be changed according to the real application. Follow data sheet guidelines for component design and selection.

The EVM can be configured in various multiphase and multioutput configurations. The default EVM is configured for four outputs. The following is a guide in terms of component connections to be made to configure the EVM in each of the possible configurations.

To configure two outputs with 1-phase configuration and 3-phase configuration, follow these steps:

  1. Depopulate EN3 and EN4 divider network (R16, R18, R23, and R25).
  2. Depopulate PG3 and PG4 resistors (R33 and R34).
  3. Depopulate SS3 and SS4 caps (C75 and C76).
  4. Depopulate COMP3 and COMP4 RC network (R37, C71, R38, C72).
  5. Depopulate FB resistor network for VOUT3 and VOUT4 (R15, R17, R19, R22, R24, and R26).
  6. Populate zero-ohm resistors in R44, R45, R46, R47, R48, R49, R50, R51, R52, and R53. With this action, VOUT1 is the single output rail and VOUT2 is the 3-phase configuration output rail.

To configure two outputs with 2-phase and 2-phase configuration, follow these steps:

  1. Depopulate EN2 and EN4 divider network (R10, R13, R23, and R25).
  2. Depopulate PG2 and PG4 resistors (R32 and R34).
  3. Depopulate SS2 and SS4 caps (C74 and C76).
  4. Depopulate COMP2 and COMP4 RC network (R36, C70, R38, C72).
  5. Depopulate FB resistor network for VOUT2 and VOUT4 (R9, R11, R14, R22, R24, and R26).
  6. Populate zero-ohm resistors in R39, R40, R41, R42, R43, R49, R50, R51, R52, and R53. With this action, VOUT1 and VOUT3 are configured in 2-phase configuration output rails.

To configure a single output with 4-phase configuration, follow these steps:

  1. Depopulate EN2, EN3, and EN4 divider network (R10, R13, R16, R18, R23, and R25).
  2. Depopulate MSEL2 resistor R21.
  3. Depopulate RT2 resistor R28.
  4. Depopulate PG2, PG3 and PG4 resistors (R32, R33, and R34).
  5. Depopulate SS2, SS3 and SS4 caps (C74, C75, and C76).
  6. Depopulate COMP2, COMP3, and COMP4 RC network (R36, C70, R37, C71, R38, and C72).
  7. Depopulate FB resistor network for VOUT2, VOUT3 and VOUT4 (R9, R11, R14,R15, R17, R19, R22, R24, and R26).
  8. Populate zero-ohm resistors in R39, R40, R41, R42, R43, R44, R45, R46, R47, R48, R49, R50, R51, R52, and R53. With this action, VOUT1 is configured in 4-phase configuration output rail.
