TPS628640BYCGR

The TPS62864 and TPS62866 are high-frequency synchronous buck converters with an I²C interface, delivering high-efficiency, adaptive, high-power-density solutions. The converter operates in PWM mode under medium-to-high load conditions and automatically enters power-save mode at light loads, maintaining high efficiency across the full load current range. The device can also be forced into PWM mode to achieve minimum output voltage ripple. With its DCS-Control architecture, the device achieves excellent load transient performance and meets stringent output voltage accuracy requirements. Output voltage can be rapidly adjusted via the I²C interface and dedicated VID pin, allowing the power consumption of the load to adapt to the application's continuously changing performance demands.
