LMR60420/LMR60420-Q1 Synchronous Buck Converter

Texas Instruments LMR60420/LMR60420-Q1 Synchronous Buck Converter is a highly efficient 3V to 36V, ultra-low IQ converter that enables high power density and low EMI. This converter offers a 1V to 20V output voltage range, including a resistor divider between the output voltage node, feedback, and ground. The LMR60420/LMR60420-Q1 converter features a power-good output for power sequencing and a MODE/SYNC pin to select between modes of operation. The current-mode control architecture with 30ns minimum on-time allows high-conversion ratios at high frequencies, easy loop compensation, fast transient response, and excellent load and line regulation. The LMR60420/LMR60420-Q1 offers variants with a spread spectrum in an ultra-compact, 2.5mm x 2mm, HotRod QFN-9 package. Typical applications include factory automation and control, appliances, and building automation.
