The TPS53513 device is a small-sized, synchronous buck converter with an adaptive on-time D-CAP3 control mode. The device offers ease-of-use and low external-component count for space-conscious power systems.

This device features high-performance integrated MOSFETs, accurate 0.5% 0.6-V reference, and an integrated boost switch. Competitive features include very low external-component count, fast load-transient response, auto-skip mode operation, internal soft-start control, and no requirement for compensation.

A forced continuous conduction mode (FCCM) helps meet tight voltage regulation accuracy requirements for performance DSPs and FPGAs. The TPS53513 device is available in a 28-pin VQFN package and is specified from –40°C to +85°C ambient temperature.
