Introduction
TPS54560BDDAR - High-Efficiency Synchronous Step-Down DC-DC Converter
Core Functions
- High-efficiency synchronous step-down DC-DC converter delivering 5A output current with up to 95% conversion efficiency
- Wide input voltage range (4.5V to 28V) compatible with industrial supplies, battery packs, and 12V/24V system rails
- Adjustable output voltage (0.8V to VIN) via external resistors for diverse load requirements
- Advanced current-mode control with fast transient response (<50μs typical) for stable output during load changes
- Comprehensive protection: overcurrent (OCP), overvoltage (OVP), undervoltage lockout (UVLO), and thermal shutdown (TSD)
- Fixed switching frequency of 500kHz (adjustable to 1MHz) enabling compact inductor/capacitor selection
- Soft-start pin (SS) for inrush current mitigation and power-good (PG) pin for system monitoring
