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 Semiconductor's 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.

FAN53200 5 A, 2.4 MHz, Digitally Programmable TinyBuck(R) Regulator Features Description The FAN53200 is a step-down switching voltage regulator that delivers a digitally programmable output from an input voltage supply of 2.5 V to 5.5 V. The 2 output voltage is programmed through an I C interface capable of operating up to 3.4 Mbps. Quiescent Current in PFM Mode: 60 A (Typical) Digitally Programmable Output Voltage: o 0.6 -1.3875 V in 12.5 mV Steps Best-in-Class Load Transient Using a proprietary architecture with synchronous rectification, the FAN53200 is capable of delivering 5 A continuously at over 80% efficiency, while maintaining over 80% efficiency at load currents as low as 10 mA. The regulator operates at a nominal fixed frequency of 2.4 MHz, which reduces the value of the external components. Additional output capacitance can be added to improve regulation during load transients without affecting stability. Inductance up to 1.2 H may be used with additional output capacitance. Continuous Output Current Capability: 5 A 2.5 V to 5.5 V Input Voltage Range Programmable Slew Rate for Voltage Transitions Fixed-Frequency Operation: 2.4 MHz 2 I C-Compatible Interface Up to 3.4 Mbps Internal Soft-Start Input Under-Voltage Lockout (UVLO) At moderate and light loads, Pulse Frequency Modulation (PFM) is used to operate in Power-Save Mode with a typical quiescent current of 60 A. At higher loads, the system automatically switches to fixedfrequency control, operating at 2.4 MHz. In Shutdown Mode, the supply current drops to 0.1 A, reducing power consumption. PFM Mode can be disabled if constant frequency is desired. The FAN53200 is available in a 20-bump, 1.6 x 2.0 mm, WLCSP.
