The TPS56623x is a 6-A, integrated, FET, synchronous buck converter that operates from 3-V to 18-V input voltage (V_IN) and 0.6-V to 7-V output voltage. The proprietary D-CAP3 control mode enables low external component count, ease of design, and optimization of the power design for cost, size, and efficiency. As the ULQ™ DC/DC converter, the device enables long battery life in system standby mode and high efficiency under light load conditions. The devices employ D-CAP3 control mode that provides fast transient response with no external compensation components and an accurate feedback voltage. The control topology provides a seamless transition between CCM operating mode in heavier load conditions and DCM operation in lighter load conditions.

Eco-mode allows the TPS566231 and TPS566231P to maintain high efficiency at light load. The TPS566238 and TPS566238P work in continuous current mode to maintain lower output ripple in all load conditions. The soft-start time of the TPS566231 and TPS566238 can be adjusted through the SS pin. The TPS566231P and TPS566238P indicate power good through the PG pin. The devices are able to adapt to both low equivalent series resistance (ESR) output capacitors, such as POS-CAP or SP-CAP, and ultra-low ESR ceramic capacitors.
