The RT6200 is a high voltage Buck converter that can support the input voltage range from 4.5V to 36V and the output current can be up to 0.6A. Current mode operation provides fast transient response and eases loop stabilization.

The chip also provides protection functions such as cycle-by-cycle current limit and thermal shutdown protection. The RT6200 is available in the SOT-23-6 package.

Applications

  • Distributed Power Systems
  • Battery Chargers
  • Pre-Regulator for Linear Regulators
  • WLED Drivers
