TPS56C20PWPR General Description

The TPS56C20PWPR is a cutting-edge synchronous DC-DC converter IC designed to meet the power requirements of micro-processors that demand precise core voltage adjustments. By utilizing voltage scaling control, this integrated circuit allows for efficient power-up and subsequent voltage programming through VID codes sent over an I2C compatible bus. With an adaptive on-time D-CAP2 mode control, the TPS56C20PWPR delivers rapid transient response without the need for additional external components. This innovative feature enables seamless transitioning between PWM mode for heavier loads and Eco-mode™ for lighter loads, ensuring optimal efficiency under varying operational conditions
