FAN4860 Datasheet, PDF (3/15 Pages) Fairchild Semiconductor – 3MHz, 5V Output Synchronous TinyBoost™ Regulator

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.

Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended operating
conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not recommend
exceeding them or designing to absolute maximum ratings.

Thermal Properties
Junction-to-ambient thermal resistance is a function of application and board layout. This data is measured with four-layer
2s2p boards in accordance to JEDEC standard JESD51. Special attention must be paid not to exceed junction temperature
TJ(max) at a given ambient temperate TA.
