FAN7621N

PFM Controller for Half-Bridge Resonant Converters

Fairchild Semiconductor 

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be

operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In

addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.

The absolute maximum ratings are stress ratings only. TA=25°C unless otherwise specified.
