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.

APPLICATION

• Point of Load (POL) applications such as drivers for

FPGA’s, microprocessors, DSP’s amplifiers, etc.

• Cellular and cordless phones, PDAs and others

• Supply voltage source for low voltage chip sets

• Portable computers

• Battery back-up supplies

• Digital cameras

• Routers

• Fiber optics

• LANS

• Image processing
