LM5035MHX/NOPB is a 20-pin half-bridge PWM controller for isolated DC-DC converters, integrating 105 V gate drivers, line-feedforward voltage-mode control, synchronous-rectifier timing, and programmable protection functions.

Best for

  • Isolated half-bridge DC-DC converters
  • Industrial power converters
  • Telecom power converters

Avoid if

  • A controller for non-isolated low-voltage buck conversion is required
  • The input supply exceeds the device VIN rating without an external bias arrangement

Check before use

  • Confirm VCC bias remains above the operating UVLO requirement
  • Validate high-side bootstrap capacitor sizing for MOSFET gate charge
  • Set synchronous-rectifier timing with tolerance margin
  • Keep current-sense components close to CS and AGND
