Industry Smallest and Low Profile

5W 1.5A DC/DC Buck Converter

with High Output Density Power

FEATURES

• Fully integrated DC/DC converter

• High efficiency over large load range

• 100% duty cycle

• Power density - more than 100W/inch

• 1uA shutdown current

• 2.7V to 6V input range (1Li+ and 3-cell NiCd or NiMH cells)

• 1.8V to 3.3V 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 5W

• Maximum current 1.5A

• Low profile

The DC/DC converter is a programmable topology

synchronized Buck converter for today’s continuous changing

portable electronic market. The DC/DC converter provides

flexibility of utilizing various battery configurations and

chemistries such as NiCd, NiMH, or Li+ with an input voltage

range of 2.7V to 6V. An additional flexibility is provided with

topology programmability to power multiple loads such as

power amplifiers, microcontrollers, or baseband logic IC’s.

For ultra-high efficiency, converters are designed to operate

in sychronous rectified PWM mode under full load while

transforming into externally controlled pulse-skipping mode

(PSM) under light load.

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.
