SY7208/SY7208B
High Efficiency 1MHz, 2A Step Up Regulator
General Description
The SY7208 and SY7208B are high efficiency boost
regulators targeted for general step-up applications.
SY7208B incorporates input over-voltage protection
and turn off the regulator when the input voltage
exceeds 7V.

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: θ JA is measured in the natural convection at TA = 25°C on a low effective single layer thermal
conductivity test board of JEDEC 51-3 thermal measurement standard.
Note 3: The device is not guaranteed to function outside its operating conditions.
