FEATURES  
DESCRIPTIO  
The LTC®3251/LTC3251-1.2/LTC3251-1.5 are 2-phase  
charge pump step-down DC/DC converters that produce a  
regulated output from a 2.7V to 5.5V input. The parts use  
switched capacitor fractional conversion to achieve twice  
the typical efficiency of a linear regulator. No inductors are  
required.VOUT isresistorprogrammablefrom0.9Vto1.6V  
or fixed at 1.2V or 1.5V, with up to 500mA of load current  
available.

Spread Spectrum, Spread Spectrum with Burst Mode  
operation, Super BurstTM mode operation and shutdown.
