Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

Integration helps to minimize 600 KHz critical inductances making component layout simpler and more efficient compared to discrete solutions. Fully Synchronous Operation with Integrated Schottky Diode on Low-Side MOSFET Boosts The FAN2110 provides for external loop compensation, Efficiency programmable switching frequency, and current limit. These features allow design flexibility and optimization. Internal Bootstrap Diode High frequency operation allows for all ceramic solutions. Power-Good Signal The summing current mode modulator uses lossless Starts up on Pre-Bias Outputs current sensing for current feedback and over-current Accepts Ceramic Capacitors on Output protection. Voltage feedforward helps operation over a wide input voltage range. External Compensation for Flexible Design Fairchilds advanced BiCMOS power process, Programmable Current Limit combined with low-R internal MOSFETs and a DS(ON) Under-Voltage, Over-Voltage, and Thermal thermally efficient MLP package, provide the ability to Shutdown Protections dissipate high power in a small package. Internal Soft-Start Output over-voltage, under-voltage, and thermal 5x6 mm, 25-Pin, 3-Pad MLP Package shutdown protections help protect the device from damage during fault conditions. FAN2110 also prevents pre-biased output discharge during startup in point-of- Applications load applications.
