DC DC Switching Controllers

PWM controllerHalf bridgeSynchronous rectifierGate driverWQFN-24105 V

LM5035CSQX/NOPB is a 24-pin WQFN half-bridge PWM controller for isolated DC-DC converters, combining 105 V high-side drive capability, 2 A peak sink drive, synchronous-rectifier timing, and protection functions.

Best for

  • Half-bridge isolated DC-DC converters
  • Industrial and telecom power supplies

Avoid if

  • A controller with integrated secondary MOSFET gate-drive power is required
  • Input voltage or high-side switch-node voltage exceeds 105 V without an appropriate external drive arrangement

Check before use

  • Validate transformer volt-second limit and feedforward ramp network
  • Validate synchronous-rectifier timing including isolator and secondary-driver delays
  • Keep current-sense and gate-drive loops short in PCB layout
