The TPS51383 and TPS51384 are the single, D-CAP3™ mode, synchronous buck converters requiring a very low external component count. The TPS51383 provides a fixed 3.36-V 8-A maximum output along with a separate 3.3-V, 100-mA maximum LDO. The TPS51384 provides a fixed 1.82-V 8-A maximum output along with a separate 1.8-V, 100-mA maximum LDO. Both support switch-over functionality, specifically designed for a notebook power system.
