TPS62843 Ultra-Low IQ Step-Down Converter

Texas Instruments TPS62843 Ultra-Low I_Q Step-Down Converter is a high-efficiency step-down converter with ultra-low operating quiescent current of typically 275nA. The device features a 4nA shutdown (typical) current when disabled. The device uses DCS-Control with a low and RF-friendly output voltage ripple to power radios.
