Series  
PFM Controlled,Step‐Up DC/DC Converter +Multi Voltage Detector  
CMOS Low Power Consumption  
■Applications  
Battery Powered Equipment  
PFM Controlled, Step-Up DC/DC Converter  
5 Level Window Comparator  
Voltage Detector × 2 ( Independent Power  
Supply )  
Various Portable Equipment  
TSSOP-16 Package  
■General Description  
The XC651A series are step-up DC/DC converter and multi voltage detector IC s.  
CMOS processes and laser trimming technology provide high accuracy and low power  
consumption.  
The XC651A comprises of a PFM controlled step-up DC/DC converter, a voltage  
detector with 4 x 5 level window comparators built-in, plus 2 other voltage detectors.  
The step-up DC/DC converter's EN pin ( chip enable ) provides power consumption  
savings when the step-up operations are not operating ( stand-by mode ).  
The series is available in a small TSSOP-16 package.  
■Features  
Independent power supply for each built-in block :  
Each of the following built-in blocks is operated by a separate power supply :  
PFM controlled, step-up DC/DC converter ( PFM DC/DC )  
5 level window comparator ( MWVD )  
Negative Logic: XC651A3 Series  
10  
Positive Logic : XC651A4 Series  
Voltage detector 1 with built-in delay circuit ( VD1 )  
Voltage detector 2 ( VD2 )  
Highly accurate set-up voltage :  
PFM controlled, step-up DC/DC converter : set-up voltage accuracy 2.5ꢀ  
5 level window comparator : set-up voltage accuracy 2ꢀ  
Voltage detectors 1, 2 : set-up voltage accuracy 2ꢀ  
Set-up voltage range :  
PFM controlled, step-up DC/DC converter : 2.0V ~ 3.0V ( selectable in 0.1V steps)  
5 level window comparator : 1.1V ~ 2.5V * ( selectable in 0.1V steps )  
Voltage detectors 1, 2 : 0.9V ~ 3.0V ( selectable in 0.1V steps )  
Operational voltage range :  
0.9V ~ 6.0V  
Small Package :  
TSSOP-16  
* Note :  
The set-up voltage of the 5 level window comparator cannot be freely set-up due to the limitations of the circuit.  
Please also note that the set-up voltage range of MWVD1 is 1.0V ~ 1.8V.
