After the initial power-up, the output voltage can be changed by codes sent to the IC via an I2C patible VID Control bus. The main control loops of the TPS566250 use the DCAP2™ mode control which provides a fast transient response with no external pensation ponents. The 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™ allows the TPS566250 to maintain high efficiency during lighter load conditions. The TPS566250 is able to adapt to both low equivalent series resistance (ESR) output capacitors such as POSCAP or SP-CAP, and ultralow ESR, ceramic capacitors. The device offers on chip overcurrent, undervoltage lockout and thermal shutdown protection.
