Description for the TPS56628
The TPS56628 is an adaptive on-time D-CAP2 mode synchronous buck converter. The TPS56628 enables system designers to complete the suite of various end-equipment power bus regulators with a cost effective, low component count, low standby current solution. The main control loop for the TPS56628 uses the D-CAP2 mode control that provides a fast transient response with no external compensation components. The adaptive on-time control supports seamless transition between PWM mode at higher load conditions and Eco-modeâ„¢ operation at light loads. Eco-modeâ„¢ allows the TPS56628 to maintain high efficiency during lighter load conditions. The TPS56628 also has a proprietary circuit that enables the device to adopt to both low equivalent series resistance (ESR) output capacitors, such as POSCAP or SP-CAP, and ultra-low ESR ceramic capacitors. The device operates from 4.5-V to 18-V VIN input. The output voltage can be programmed between 0.76 V and 5.5 V. The TPS56628 is available in the 8-pin DDA package, and designed to operate from –40°C to 85°C.
