TPS53513 High-Efficiency 8 A DC/DC Converter

1.5 to 18 V input, synchronous step-down SWIFT™ converter from Texas Instruments

Image of Texas Instruments' TPS53513 High-Efficiency 8 A DC/DC ConverterTexas Instruments' TPS53513 is a small-sized, synchronous buck converter with an adaptive on-time D-CAP3 control mode. The device offers ease-of-use, 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 helps meet tight voltage-regulation accuracy requirements for performance DSPs and FPGAs. The TPS53513 is available in a 28-pin QFN package and is specified from –40°C to 85°C ambient temperature.

Features Applications
