FAN5631/FAN5632  
Regulated Step-Down Charge Pump DC/DC Converter  
Features  
Description  
■ 90% Peak Efficiency  
The FAN5631/FAN5632 is an advanced, third-generation  
switched capacitor step-down DC/DC converter utilizing Fair-  
child's proprietary ScalarPump™ technology. This innovative  
architecture utilizes scalar switch re-configuration and fractional  
switching techniques to produce low output ripple, lower ESR  
spikes, and improve efficiency over a wide load range.  
■ Low EMI  
■ Low Ripple  
■ Selectable Output Voltage 1.2V/1.5V for FAN5631  
■ Efficiency Optimizer Feature for FAN5632  
■ Input Voltage Range: 2.2V to 5.5V  
■ Output Current: Up to 250mA  
The FAN5631/FAN5632 produces a fixed regulated output volt-  
age from an input voltage of 2.2V to 5V. Customized output volt-  
ages are available in 100mV increments from 1V to 1.8V.  
Contact a Fairchild sales representative for customized output  
voltage options.  
■
5% Output Voltage Accuracy  
■ 30µA Operating Current  
■ I < 1µA in Shutdown Mode  
CC  
■ 1.5MHz Operating Frequency  
In order to maximize efficiency, the FAN5631/5632 achieves  
regulation by skipping pulses. Depending upon load current, the  
size of the switches are scaled dynamically; consequently,  
current spikes and EMI are minimized. An internal soft-start  
circuitry prevents excessive current drawn from the supply. The  
device is internally protected against short circuit and over  
temperature conditions.  
■ Shutdown Isolates Output from Input  
■ Soft-Start Limits In-Rush Current  
■ Short Circuit and Over Temperature Protection  
■ Minimum External Component Count  
■ Available in a 3x3mm 10-Lead MLP Package  
The FAN5631 has a dual output voltage feature. When V

high, V  
is 1.5V and when V  
is low, V  
is 1.2V. Other

output voltage options are available upon request.  
■ Handheld Computers  
■ Portable Electronic Equipment  
■ Core Supply to Next Generation Processors  
■ Low Voltage DC Bus  
■ Digital Cameras  
In addition, the FAN5632 has an efficiency optimizer feature  
that, when enabled, changes the switch mode configuration  
from 2:1 to 1:1 at the lower threshold of V . The efficiency is  
IN  
then maintained at its peak level over a wider range of input volt-  
ages. In addition, V  
will vary between 1.2V to 1.5V as a  
OUT  
result of this efficiency optimization. If the efficiency optimizer is  
not enabled, V is regulated to 1.5V.  
■ DSP Supplies

Both the FAN5631 and FAN5632 are available in a 3x3mm  
10-lead MLP package.
