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.

Output Voltage Range: 0.8 V to 80% V IN The FAN2106 contains both synchronous MOSFETs Over 95% Peak Efficiency and a controller/driver with optimized interconnects in one package, which enables designers to solve high- 1% Reference Accuracy Over Temperature current requirements in a small area with minimal Programmable Frequency Operation: 200 KHz to external components. 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 FAN2106 provides for external loop Efficiency compensation, programmable switching frequency, and current limit. These features allow design Internal Bootstrap Diode flexibility and optimization. High-frequency operation Internal Soft-Start allows for all-ceramic solutions. Power-Good Signal The summing current-mode modulator uses lossless Starts on Pre-Biased Outputs current sensing for current feedback and over-current protection. Voltage feedforward helps operation over Accepts Ceramic Capacitors on Output a wide input voltage range. External Compensation for Flexible Design Fairchilds advanced BiCMOS power process, Programmable Current Limit combined with low-RDS(ON) internal MOSFETs and a Under-Voltage, Over-Voltage, and Thermal thermally efficient MLP package, provide the ability to Protections dissipate high power in a small package. 5x6 mm, 25-Pin, 3-Pad MLP Package Output over-voltage, under-voltage, over-current, and thermal shutdown protections help protect the device Applications from damage during fault conditions. FAN2106 prevents pre-biased output discharge during startup Servers & Telecom in point-of-load applications.
