Low Profile 3mm DC/DC Buck Converter
0.9V to 1.3V, 3A with 111W/in3 Power Density
Efficiency up to 95%
FEATURES
• Fully integrated DC/DC converter
• Advanced development of FX5545G305
• High efficiency over large load range
• 100% duty cycle
• Power density - more than 111W/inch3
• 1µA shutdown current
• 2.5V to 6V input range (1Li+ and 3-cell NiCd or NiMH cells)
• 0.9V to 1.3V output voltage
• Programmable PWM/PSM controls
• Low output ripple
• BGA construction
• Temperature range: - 40°C to + 85°C
• No external components required
• Output power 3.9W
• Maximum current 3A
• Low profile
• UL recognized component E250930
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.
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 2.5V 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.
APPLICATION
• 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
