RT6220DH

6A, 23V, 500kHz, ACOTTM Synchronous Buck Converter

RT6220DH
New

The RT6220DH is a synchronous Buck converter with Advanced Constant On-Time (ACOTTM) mode control, which provides a very fast transient response with no external compensators. The RT6220DH operates from 4.5V to 23V input voltage, provides complete protection functions including Over Current Protection (OCP), Under Voltage Protection (UVP) and Over Voltage Protection (OVP). This IC also provides a 1.5ms internal soft-start function and an open-drain power good indicator.

Applications

  • Laptop Computers
  • Tablet PCs
  • Networking Systems
  • Servers
  • Personal Video Recorders
  • Flat Panel Television and Monitors
