3 Description
The TPS65133 is designed to supply any system
requiring ±5.0-V supply rails. Each output can supply
up to 250 mA of output current. The input supply
voltage range is suitable for use with lithium ion
batteries or from a fixed 3.3-V supply.
Efficiency is typically over 90% for most applications
(operating from a lithium ion battery, output currents
in the range 50 mA to 200 mA). The two converters in
the TPS65133 device operate independently,
allowing 100% mismatch between positive and
negative output currents.
