Industry Smallest and Low Profile
10W 2A DC/DC Boost 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 380W/inch3
• 1uA shutdown current
• 2.7V 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 construction
• Temperature range: - 40°C to + 85°C
• No external components needed
• Output power 10W
• Maximum current 2A
• Low profile
The DC/DC converter is a programmable topology
synchronized Boost 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 input voltage
range of 2.5V to 6V. An additional flexibility is provided with
topology programmibility to power multiple loads such as
power amplifiers, microcontrollers, or base band 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.
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.
APPLICATION
• Cordless phones, PDAs and others
• Supply voltage source for low-voltage chip sets
• Portable computers
• Battery back-up supplies
• Cameras
