The TPS51383 and TPS51384 are monolithic 8-A synchronous buck converters with adaptive on-time D-CAP3 control mode. Integrated low RDS(on) power MOSFETs enable high efficiency and offer ease-of-use with minimum external component count for space-constrained power systems. Features include an accurate reference voltage, fast load transient response, auto-skip mode operation for light load efficiency, OOA light load operation with > 25-kHz switching frequency, D-CAP3 control mode with good line, load regulation, and does not require external compensation.

The TPS51383 provides a fixed 3.36-V 8-AMAX output and a 3.3-V, 100-mAMAX LDO output with switch-over functionality. The TPS51384 provides a fixed 1.82-V 8-AMAX output and a 1.8-V, 100-mAMAX LDO with switch-over functionality. Both the TPS51383 and TPS51384 have ultra-low quiescent current function for long battery life in system standby mode.

The TPS5138x are available in a thermally enhanced 12-pin QFN package and are designed to operate from –40°C to 125°C junction temperature.
