RT8106/A
5V/12V Synchronous Buck PWM DC-DC Controller
General Description
The RT8106/A is a DC/DC synchronous buck PWM
controller with embedded driver support up to 12V+12V
boot-strapped voltage for high efficiency power driving. The
part integrates full functions of voltage regulation, power
monitoring and protection into a single small footprint
WDFN-10L 3x3 (Exposed Pad) package.
The RT8106/A adopts a high-gain voltage mode PWM
control for simple application design. An internal 0.8V
reference allows the output voltage to be precisely
regulated for low voltage requirement. Based on all
RT8106/A features, the part provides an optimum
compromise between efficiency, total B.O.M. count, and cost.

Note 1. Stresses listed as the above "Absolute Maximum Ratings" may cause permanent damage to the device. These are for
stress ratings. 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 for extended
periods may remain possibility to affect device reliability.
Note 2. θJA is measured in the natural convection at TA = 25°C on a low effective thermal conductivity test board of
JEDEC 51-3 thermal measurement standard. The case point of θJC is on the expose pad of the package.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
