RT6200
0.6A, 36V, 1.2MHz Step-Down Converter
General Description
Features
Wide Operating Input Voltage Range : 4.5V to 36V
Adjustable Output Voltage Range : 0.8V to 15V
0.6A Output Current
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.
0.35Ω Internal Power MOSFET Switch
High Efficiency up to 95%
1.2MHz Fixed Switching Frequency (Duty <90%)
Support duty up to 95%
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.
Stable with Low ESR Output Ceramic Capacitors
Thermal Shutdown
Cycle-By-Cycle Over-Current Protection
