Texas Instruments TPS43060 | Demoboard TIDA-01558

Beschreibung

This analog, bidirectional power conversion reference design has a discharge or boost stage of 500 W and charge or buck stage of 50 W. This reference design is made for 24-V battery pack and 30-V to 38-V bus voltage for use in DC-UPS, battery backup unit (BBU), local energy storage (LES) and DC/DC brick modules. The design’s high efficiency of >98% discharge and >95% charge optimizes the thermal management and extends battery backup time.
