LM5169FDDAR

Voltage Regulators - DC DC Switching Regulators

120 V buck converter0.65 AFPWMFly-BuckSO PowerPAD

LM5169FDDAR is a 120-V synchronous buck regulator rated for up to 0.65 A and configured for FPWM operation, making it suitable for wide-input industrial and Fly-Buck power designs.

Best for

  • Wide-input industrial buck converters
  • High-cell-count battery-pack power rails
  • FPWM Fly-Buck converter designs

Avoid if

  • The application requires more than 0.65 A output current.
  • The input voltage or transients exceed the recommended operating conditions without suitable system protection.

Check before use

  • Output voltage divider and feedback ripple injection
  • Inductor saturation and peak current
  • Bootstrap capacitor effective capacitance
  • PowerPAD soldering, thermal vias, and junction temperature
