FAN53555  
5 A, 2.4 MHz, Digitally  
Programmable TinyBuck®  
Regulator  
Description  
www.onsemi.com  
The FAN53555 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 output voltage is programmed through an I C  
2
interface capable of operating up to 3.4 MHz.  
Using a proprietary architecture with synchronous  
• 2.5 V to 5.5 V Input Voltage Range  
rectification, the FAN53555 is capable of delivering 5 A  
continuous at over 80% efficiency, while maintaining over  
80% efficiency at load currents as low as 10 mA. Pulse  
currents as high as 6.5 A can be supported by the 05 option.  
The regulator operates at a nominal fixed frequency of  
2.4 MHz, which reduces the value of the external  
components to 330 nH for the output induction and as low  
as 20 mF for the output capacitor. Additional output  
capacitance can be added to improve regulation during load  
transients without affecting stability. Inductance up to  
1.2 mH may be used with additional output capacitance.  
At moderate and light loads, Pulse Frequency Modulation  
(PFM) is used to operate in Power−Save Mode with a typical  
quiescent current of 60 mA. Even with such a low quiescent  
current, the part exhibits excellent transient response during  
large load swings. At higher loads, the system automatically  
switches to fixed−frequency control, operating at 2.4 MHz.  
In Shutdown Mode, the supply current drops below 1 mA,  
reducing power consumption. PFM Mode can be disabled if  
constant frequency is desired. The FAN53555 is available in  
a 20−bump, 1.6 x 2 mm, WLCSP.
