FAN49103 — 2.5 A, 1.8 MHz, TinyPower™ I2C Buck-  
Boost Regulator  
Features  
Description

.
.
.
.
24 µA Typical PFM Quiescent Current  
Above 95% Efficiency  
Total Layout Area = 11.61 mm2  
Input Voltage Range: 2.5 V to 5.5 V  
Maximum Continuous Load Current:  
The FAN49103 is a high efficiency buck-boost switching  
mode regulator which accepts input voltages either  
above or below the regulated output voltage. Using full-  
bridge architecture with synchronous rectification, the  
FAN49103 is capable of delivering up to 2.5 A while  
regulating the output at 3.4 V. The FAN49103 exhibits  
seamless transition between step-up and step-down  
modes reducing output disturbances. The output voltage  
and operation mode of the regulator can be  
programmed through an I2C interface.

3.0 A at VOUT=3.4 V, VIN=3.3 V  
2.5 A at VOUT=3.4 V, VIN=3.0 V  
2.0 A at VOUT=3.4 V, VIN=2.5 V  
At moderate and light loads, Pulse Frequency  
Modulation (PFM) is used to operate the device in  
power-save mode to maintain high efficiency. In PFM  
mode, the part still exhibits excellent transient response  
during load steps. At moderate to heavier loads or  
Forced PWM mode, the regulator switches to PWM  
fixed-frequency control. While in PWM mode, the  
regulator operates at a nominal fixed frequency of  
1.8 MHz, which allows for reduced external component  
values.
