Product Description: 

The LM27402SQ is a voltage mode synchronous DC/DC buck controller with lossless inductor DCR current sensing. Sensing inductor current without the need for additional resistive power transfer system components improves overall efficiency and facilitates the continuous execution of accurate current sensing, while a 0.6V ±1% voltage reference ensures high accuracy and low voltage characteristics at the output.The LM27402SQ has an input operating voltage range of 3V to 20V, and is suitable for use with a wide range of input power supply rails.
