TPS53513 www.ti.com SLUSBP9A – SEPTEMBER 2013 – REVISED DECEMBER 2013 1.5 to 18 V (4.5 to 25 V bias) Input, 8-A Single Synchronous Step-Down SWIFT Converter 1 FEATURES Integrated 13.8 and 5.9 mΩ MOSFETs With 8-A Continuous Output Current Supports All Ceramic Output Capacitors Reference Voltage 600 mV ±0.5% Tolerance Output Voltage Range: 0.6 V to 5.5 V D-CAP3 Control Mode With Fast Load-Step Response Auto-Skipping Eco-mode for High LightLoad Efficiency FCCM for Tight Output Ripple and Voltage Requirements Eight Selectable Frequency Settings from 200 kHz to 1 MHz Pre-Charged Startup Capability Built-in Output Discharge Circuit Open-Drain Power-Good Output 3.5-mm × 4.5-mm, 28-Pin, QFN Package PGOOD VIN APPLICATIONS Server and Cloud-Computing POLs Broadband, Networking, and Optical Communications Infrastructure I/O Supplies Supported at the WEBENCH Design Center 2 DESCRIPTION The TPS53513 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 loadtransient 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 requ……
