Texas Instruments TPS65132 Dual Output Power Supply

Texas Instruments TPS65132 Dual Output Power Supply is designed to supply positive/negative driven applications. The device uses a single inductor scheme for both outputs to provide the user with the smallest solution size, a small bill of material, and high efficiency. The devices offer line and load regulation at low noise. With its input voltage range of 2.5V to 5.5V, it is optimized for products powered by single-cell batteries (Li-Ion, Ni-Li, Li-Polymer) and fixed 3.3V and 5V rails. The Texas Instruments TPS656132 provides 80mA and 150mA output current options with programmability to 40mA.
