Single Inductor - Dual Output Power Supply for Bipolar, Small-/Medium-Size Displays - TPS65132S

TPS65132S (ACTIVE)

Single Inductor - Dual Output Power Supply for Bipolar, Small-/Medium-Size Displays

 

Description

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