• Power Density- more than 80W/inch³

• 1uA shutdown current

• 2.5V to 6V input range (1 Li+ and 3-cell NiCd or NiMH cells)

• 3.3V to 6V output voltage with max. output current of 500mA

• Programmable PWM/PSM controls

• Low output ripple

• BGA/LGA construction

• Temperature range: - 40°C to 85°C

• No external components needed

• Low profile

The DC/DC converter provides fully integrated synchronous

boost converter solution for the latest one-cell lithium ion cellular

phones. Its input voltage is between 2.5V to 6V, capable of

delivering up to 500mA of output current at 3.3V to 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 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

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.

APPLICATION

• 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
