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.

It Over 95% Efficiency enables designers to solve high current requirements in a small area with minimal external components. Fully Synchronous Operation with Integrated Schottky Diode on Low-side MOSFET Boosts External compensation, programmable switching Efficiency frequency, and current limit features allow for design optimization and flexibility. Programmable Frequency Operation (200 KHz to 600 KHz) The summing current mode modulator uses lossless current sensing for current feedback and over-current, Power-good Signal and includes voltage feedforward. Accepts Ceramic Capacitors on Output Fairchilds advanced BiCMOS power process, combined External Compensation for Flexible Design with low R internal MOSFETs and a thermally DS(ON) efficient MLP package provide the ability to dissipate Wide Input Range: 3 V to 24 V high power in a small package. Output Voltage Range: 0.8 V to 90%V IN Output over-voltage, under-voltage, and thermal Input Under-Voltage Lockout shutdown protections plus power-good, help protect the devices from damage during fault conditions.
