Efficiency at 6-A Loads The TPS54618-Q1 provides accurate regulation for a • 300-kHz to 2-MHz Switching Frequency variety of loads with an accurate ±1% voltage • 0.8-V ±1% Voltage Reference Over Temperature reference (VREF) over temperature. (–40°C to 150°C) Efficiency is maximized through the integrated • Synchronizes to External Clock 12-m Ω MOSFETs and 515-μA typical supply current. • Adjustable Slow-Start and Sequencing Using the enable pin, shutdown supply current is • UV and OV Power-Good Output reduced to 5.5-µA by entering a shutdown mode. • Thermally-Enhanced 3-mm × 3-mm, 16-pin Undervoltage lockout is internally set at 2.6 V, but WQFN Package can be increased by programming the threshold with a resistor network on the enable pin. The output- 2 Applications voltage startup ramp is controlled by the slow-start pin. An open-drain power-good signal indicates the • Low-Voltage, High-Density Power Systems output is within 93% to 107% of its nominal voltage. • Point-of-Load Regulation for High-Performance Frequency foldback and thermal shutdown protect the DSPs, FPGAs, ASICs, and Microprocessors device during an overcurrent condition. • Broadband, Networking, and Optical TPS54618-Q1 is supported in the SwitcherPro™ Communications Infrastructure software tool at www.ti.com/switcherpro.
