8.1 Overview

The TPS568230 is 8-A integrated FET synchronous buck converter which operates from 4.5V to 18V input voltage (VIN), and the output is from 0.6V to 7V. The proprietary D-CAP3™ mode enables low external component count, ease of design, optimization of the power design for cost, size and efficiency. The key feature of the TPS568230 is ultra-low quiescent current (ULQ™) mode. This feature is beneficial for long battery life in system standby mode. The device employs D-CAP3™ mode control that provides fast transient response with no external compensation components and an accurate feedback voltage. The control topology provides seamless transition between CCM operating mode at higher load condition and DCM operation at lighter load condition. Eco-mode™ allows the TPS568230 to maintain high efficiency at light load. OOA (out of audio) mode makes switching frequency above audible frequency larger than 25 kHz, even there is no loading at output side. FCCM mode has the constant switching frequency at both light and heavy load. The TPS568230 is able to adapt to both low equivalent series resistance (ESR) output capacitors such as POSCAP or SP-CAP, and ultra-low ESR ceramic capacitors.
