• Note: For higher output voltage please
consult factory at FunctionPAK@Vishay.com
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 is available in 20-ports BGA/LGA
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.
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.
