TPS56428 Synchronous Step-Down Converters Texas Instruments TPS56428 Synchronous Step-Down Converters are a D-CAP2 mode synchronous buck converter that is optimized for various power bus regulation applications. It meets power bus regulation needs with a cost-effective, low component count, low standby current solution. The D-CAP2 mode control provides a fast transient response with no external compensation components. This adaptive on-time control supports seamless transition between PWM mode at higher load conditions and advanced Eco-mode operation at light loads. Advanced Eco-mode™ maintains higher efficiency during lighter load conditions than traditional skip mode. The TPS56428 also has a proprietary circuit to adapt to both low equivalent series resistance (ESR) output capacitors, such as POSCAP or SP-CAP, and ultra-low ESR ceramic capacitors.
