The trade-off is layout sensitivity: the high di/dt edges demand a tight loop from the input capacitor through the internal high-side FET, the external Schottky catch diode, and back to the cap ground — the datasheet layout guide should be followed, not just read. Because the part is non-synchronous (no internal low-side FET), an external Schottky rectifier is required per channel. The catch diode's forward voltage and reverse leakage at the operating temperature directly affect efficiency, particularly at light loads — a 0.4–0.5 V Vf Schottky in a SOD-123 or SMA package is a typical match for the 2 A output.","metaTitle":"MIC4742YML-TR Buck Regulator, Dual 2A, 2MHz, 16-MLF","metaDescription":"Active Microchip MIC4742YML-TR dual 2A step-down buck regulator, 2.9-5.5V input, 2MHz switching, 16-MLF package, -40 to +125°C.
