The DC/DC converter provides fully integrated synchronous
buck converter solution for the latest one-cell lithium ion cellu-
lar phones. Its input voltage is between 2.7V to 6V, capable of
delivering up to 600mA of output current, an output voltage
between 1.5V to 3.6V can be adjusted an external resistor
according 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 25mV.
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

ORDERING INFORMATION
APPLICATION
Cordless phones, PDAs and others
Supply voltage source for low voltage chip sets
Portable computers
Battery back-up supplies
Cameras
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
°C to + 85°C.
