Industry Smallest and Low Profile

3W DC/DC Boost Converter

with High Output Density Power

FEATURES

• Fully integrated DC/DC converter

• High efficiency over large load range

• 2MHz switching frequency

• 100% duty cycle

• Power density - more than 100W/inch

• 1uA shutdown current

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

• 3.3V to 6V output voltage

• Programmable PWM/PSM controls

• Low output ripple

• BGA/LGA construction

• Temperature range: - 40°C to + 85°C

• No external components needed

• Output power 3W

• Maximum current 600mA

• Low profile

The DC/DC converter provides fully integrated synchronous

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

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

of delivering up to 600mA 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 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.

The DC/DC converter is available in 20-ports BGA package.

In order to satisfy the stringent ambient temperature require-

ments, the DC/DC converter is designed to handle the indus-

trial temperature range of - 40°C to + 85°C.

APPLICATION

•

Cordless phones, PDAs and others

Supply voltage source for low voltage chip sets

Portable computers

Battery back-up supplies

Cameras
