RT8409
Green Mode Buck Converter
General Description
The RT8409 integrates a power MOSFET controller. It is
used for step down converters by well controlling the
internal MOSFET and regulating a constant output voltage.
The RT8409 features few system component counts and
simple system design. Especially, the RT8409 can use a
cheap simple drum core inductor in the system instead
of an EE core while maintaining the high efficiency.
The RT8409 is housed in a SOP-8 package. The
components of the whole system can be made very
compact.

Note 1. Stresses beyond those listed “Absolute Maximum Ratings” may cause permanent damage to the device. These are
stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions may affect
device reliability.
Note 2. θJA is measured under natural convection (still air) at TA = 25°C with the component mounted on a low effective-thermal-
conductivity two-layer test board on a JEDEC thermal measurement standard.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
