The DC/DC converter provides fully integrated synchronous
buck converter solution for the latest one-cell lithium ion
cellular phones. Its input voltage is between 2.7V to 6V,
capable of delivering 600mA of output current at 1.5V to 3.6V.
The DC/DC converter combines the 2MHz-switching
controller with fully integrated passive components needed
to deliver the smallest and most efficient converter available
today. The high switching frequency minimizes the output
capacitance with peak to peak output ripple as low as 20mV.
The DC/DC converter delivers efficiency up to 95%.
The programmable pulse-skipping mode (PSM) maintains
this high efficiency even during the standby and idle modes
to increase overall battery life and talktime. In order to extract
the last ounce of power from the battery, the DC/DC converter
is designed with 100% duty cycle control for this mode. This
function enables the DC/DC converter to operate like a
saturated linear regulator delivering the highest potential
