LвЂ‰DESIGN IDEAS USB Power Manager with
High Voltage 2A Bat-Track
Buck Regulator by Nancy Sun Introduction
Personal navigation devices, HDDbased media players, automotive
accessories, and other handheld products draw on an array of power sources
for recharging their batteries. These
sources include USB (nominally 5V),
low voltage wall adapters (4.5-5.5V),
high voltage wall adapters (12VвЂ“24V),
FireWire (8VвЂ“33V) and automotive
batteries (nominally 12V). The large
supply of available sources leads to an
increasing need for handheld devices
that can accept a wide range of multiple
input voltages without the need for
myriad external power adapters.
The LTC4090 is designed to accommodate both USB and high voltage
sources by integrating a high voltage
2A switching buck regulator, a USB
input, a PowerPathв„ў controller and a
linear battery charger into a compact,
thermally enhanced 3mm Г— 6mm
