Descripción de TPS56720
The TPS56X20 is a synchronous DC-DC converter IC (integrated circuit) with a voltage scaling control to power up micro-processors (MCUs) requiring core voltage (VCORE) tune-ups. After the initial power-up, the output voltage can be programmed/scaled by VID codes sent over an I2C compatible bus.
This step-down (buck) converter employs an adaptive on-time D-CAP2 mode control which provides a very fast transient response with no external components. Unlike traditional voltage-/current-mode controls, the D-CAP2 supports seamless transition between PWM mode for higher load and Eco-mode™ for light load. Eco-mode maintains high efficiency in light-load.
The TPS56X20 supports both ultra-low ESR ceramic capacitors and low equivalent series resistance (ESR) output capacitors, such as POSCAP or SP-CAP. The device is optimized for a small 1.0µH to 2.2µH inductor saving PCB area.
The TPS56X20 devices are available in the HTSSOP package.
