TPS65133DPDR

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.
