TPS659102A1RSLR

Product Summary

The TPS659102A1RSLR is an integrated power-management IC available in 48-QFN package and dedicated to applications powered by one Li-Ion or Li-Ion polymer battery cell or 3-series Ni-MH cells, or by a 5-V input; it requires multiple power rails. The TPS659102A1RSLR provides three step-down converters, one step-up converter, and eight LDOs and is designed to support the specific power requirements of OMAP-based applications. The applications of the TPS659102A1RSLR are (1)Portable and handheld systems; (2)OMAP3 power management.
