Fully Integrated DC/DC Converter 0.9V to 6V, 4A with

570W/in³Power Density, Efficiency up to 95%.

Surface Mount Package for Prototyping

FEATURES

• Fully integrated DC/DC converter

• No external components required

• Buck or Boost configurations

• High efficiency over large load range

• 100% duty cycle

• Power density - more than 570W/inch³

• 1µA shutdown current

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

• 0.9V to 6V output voltage

• Programmable PWM/PSM controls

• Low output ripple

• Standard socket construction or plug-in for prototype

(use for BGA production)

• Temperature range: - 40°C to + 85°C

• Output power 15W

• Maximum continuous current 4A

The DC/DC converter is

a programmable topology

APPLICATIONS (BGA)

synchronized Buck or Boost converter for today’s continuous

changing 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 2.5V 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 synchronous rectified PWM mode under full load while

transforming into externally controlled pulse-skipping mode

(PSM) under light load.

• Cordless phones, PDAs and others

• Supply voltage source for low-voltage chip sets

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

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

• Portable computers

• Battery back-up supplies

• Cameras

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

for production. Convenient 8-pin plug-in modules are

available for prototyping. 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, with no cooling or derating.

DESCRIPTION

Logic low on SD pin shuts down the FunctionPAK completely and decreases current consumption to less than 1 µA.

PWM/PSM Logic high = PWM mode, logic low = PSM mode. In PSM mode synchronous rectification is disabled.

Externally controlled synchronization signal. Logic high to low transition forces the clock synchronization.

If not used the pin must be connected to Vin or logic high.
