Compact integrated PMU for applications requiring high power conversion efficiency

The Texas Instruments (TI) TPS65400 integrated power management unit (PMU) is now available from Mouser stock. The integrated PMU is optimized for applications requiring small form factor and high power conversion efficiency, enabling small space-constrained equipment with high ambient operating temperature without cooling. The device provides high-power efficiency at a system level by enabling a single stage conversion from an intermediate distribution bus with an optimized combination of regulators. Applications include small cellular base stations (for example: picocells and microcells) and macro systems (using multiple PMUs); Power over Ethernet (PoE) powered communications infrastructure equipment; automotive Infotainment and telematics powering DSPs and MCUs; industrial and factory automation; and systems requiring small form factor, high-efficiency, high-ambient operating temperature, and flexible power management.
