                Description for the LMQ61460-Q1<\/h2>\n
                \n

                The LMQ61460-Q1 is a high-performance, DC-DC synchronous buck converter with integrated bypass capacitors. With integrated high-side and low-side MOSFETs, up to 6 A of output current is delivered over a wide input range of 3.0 V to 36 V; 42-V tolerance supports load dump for durations of 400 ms. The device implements soft recovery from dropout eliminating overshoot on the output.<\/p>\n

                The device is specifically designed for minimal EMI. The device incorporates pseudo-random spread spectrum, integrated bypass capacitors, adjustable SW node rise time, low-EMI VQFN-HR package featuring low switch node ringing, and optimized pinout for ease of use. The switching frequency can be synchronized between 200 kHz and 2.2 MHz to avoid noise sensitive frequency bands. In addition the frequency can be selected for improved efficiency at low operating frequency or smaller solution size at high operating frequency.<\/p>\n

                Auto-mode enables frequency foldback when operating at light loads, allowing an unloaded current consumption of only 7 \u00b5A (typical) and high light load efficiency. Seamless transition between PWM and PFM modes, along with very low MOSFET ON resistances and an external bias input, ensures exceptional efficiency across the entire load range.<\/p>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
