The DC/DC converter provides fully integrated synchronous
boost converter solution for the latest one-cell lithium ion cel-
lular phones. Its input voltage is between 2.5V to 6V, capable
of delivering 500mA of output current, an output voltage be-
tween 3.3V to 6V can be adjusted an external resistor accord-
ing to the formula:

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
output voltage for longer talk time.
The DC/DC converter is available in 20-ports BGA/LGA pack-
age. In order to satisfy the stringent ambient temperature re-
quirements, the DC/DC converter is designed to handle the
industrial temperature range of - 40擄C to + 85擄C.
