LTC3100  
1.5MHz Synchronous Dual  
Channel DC/DC Converter  
and 100mA LDO  
FEATURES  
DESCRIPTION  
The LTC®3100 combines a high efficiency 700mA syn-  
chronous step-up converter, a 250mA synchronous  
step-down converter and a 100mA LDO regulator. The  
LTC3100 features a wide input voltage range of 0.65V to  
5V.Thestep-downconvertercanbepoweredbytheoutput  
of the step-up converter or from a separate power source  
between 1.8V and 5.5V. The LDO can also be used as a  
sequencing switch on the output of the boost.

print by allowing the use of tiny, low profile inductors and  
ceramic capacitors. The switching regulators use current  
mode control and are internally compensated, reducing  
external parts count. Each converter automatically transi-  
tions to Burst Mode operation to maintain high efficiency  
over the full load range. Burst Mode operation can be  
disabled for low noise applications. The integrated LDO  
provides a third low noise, low dropout supply.

Anti-ringing circuitry reduces EMI by damping the boost  
inductor in discontinuous mode. Additional features  
include shutdown current of under 1μA and overtem-  
perature shutdown. The LTC3100 is housed in a 16-lead  
3mm × 3mm 0.75mm QFN package.
