TPS51386 Synchronous Buck Converter Texas Instruments TPS51386 Synchronous Buck Converter is a monolithic synchronous buck converter with adaptive on-time D-CAP3 control mode. This device exhibits a 4.5V to 24V input voltage range, 0.6V to 5.5V output voltage range, 8A continuous current (IOUT), and 84μA low quiescent current. The TPS51386 incorporates integrated low RDS(on) power MOSFETs to enable high efficiency and offer ease of use with minimum external component count for space-constrained power systems. This synchronous buck converter features accurate reference voltage, fast-load transient response, auto-skip mode operation for light-load efficiency, and Out-of-Audio™ (OOA) light-load operation with >,25kHz switching frequency.
