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 up to 1000mA 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 25mV.
The DC/DC converter delivers efficiency up to 95%.
The programmable pulse-skipping mode (PSM) maintains
this 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 package.
In order to satisfy the stringent ambient temperature
requirements, the DC/DC converter is designed to handle
the industrial temperature range of - 40°C to + 85°C.
