LV5980MC: Buck Converter, Switching Regulator, 1-Channel

LV5980MC is a 1 channel DC-DC converter with built-in power P-channel MOSFET. The recommended operating range is 4.5 V to 23 V. The maximum current is 3 A. The operating current is about 63 µA, and low power consumption is achieved.

Features
  • 1 channel SBD rectification DC-DC converter with built-in power P-channel MOSFET
  • Typical value of light load mode current is 63 µA
  • 4.5 V to 23 V operating input voltage range
  • 100 mΩ high-side switch
  • Output voltage adjustable to 1.235 V
  • The oscillatory frequency is 370 kHz
  • built-in OCP circuit with P-by-P method
  • When P-by-P is generated continuously, it shifts to the HICCUP operation
  • External capacitor soft-start
  • Under voltage lock-out, thermal shutdown
