Product Summary
The TPS65021RHAT is an integrated Power Management IC for applications powered by one Li-IonorLi-Polymer cell, and which require multiple power rails. The TPS65021RHAT provides three highly efficient, step-down converters targeted at providing the core voltage, peripheral, I/O and memory rails in a pro-for Processor Core (VDCDC3)cessor based system. All three step-down converters enter a low-power mode at light load for maximum efficiency across the widest possible range of load(VRTC)currents. The applications of the TPS65021RHAT include PDA, Cellular/Smart Phone, Internet Audio Player, Digital Still Camera, Digital Radio Player, Split Supply DSP and μP Solutions: OMAP1610, OMAP1710, OMAP330, Intel PXA270, etc.
