Step-Down Regulator 2.95V to 6V Input, 2A, 2MHz Synchronous Step Down SWIFT DC-DC Converter Conv DC-DC 2.95V to 6V Step Down Single-Out 0.8V to 4.5V 2A 16Pin WQFN EP T/R
TheTPS54218 device is a full featured 6-V, 2-A, synchronous, step-down, current mode converter with two integrated MOSFETs.
The TPS54218 device enables small designs by integrating the MOSFETs, implementing current mode control to reduce external component count, reducing inductor size by enabling up to 2-MHz switching frequency, and minimizing the device footprint with a small, 3 mm x 3 mm, thermally enhanced, QFN package.
The TPS54218 device provides accurate regulation for a variety of loads with an accurate ±1% voltage reference (VREF) over temperature.
Efficiency is maximized through the integrated 30-mΩ MOSFETs and a 350-μA typical supply current. Using the enable pin, shutdown supply current is reduced to 2 μA by entering a shutdown mode.
Undervoltage lockout is internally set at 2.6 V, but can be increased by programming the threshold with a resistor network on the enable pin. The output voltage startup ramp is controlled by the soft-start pin. An open-drain power good signal indicates the output is within 93% to 107% of its nominal voltage. Frequency fold back and thermal shutdown protects the device during an overcurrent condition.
