LM5171PHPR is a dual-channel bidirectional PWM controller for high-power buck/boost conversion between HV and LV power rails.

Best for

  • Bidirectional battery and supercapacitor power conversion
  • Two-phase or multiphase high-current DC/DC stages
  • Battery test systems

Avoid if

  • A fully integrated power stage is required
  • No external compensation or current sensing can be implemented
  • A voltage rating above the documented 80 V recommended HV operating limit is required

Check before use

  • Confirm MOSFET transient voltage margin and gate charge against the 5 A peak drivers.
  • Use Kelvin connections and low-inductance current-sense resistors.
  • Validate buck and boost loop compensation over voltage, load, and direction changes.
