For a 37 V output from 2.5 V input, the maximum output current is limited by the switch current and efficiency. ## 2.5 MHz switching — inductor and capacitor selection The part is not synchronously rectified, so the Schottky diode's forward voltage adds to the loss budget. No pin-compatible second source or official successor is listed, so single-source risk applies for production builds.","metaTitle":"MIC2251-2YD5-TR Boost Converter, 2.5-5.5V Input, 37V Output","metaDescription":"MIC2251-2YD5-TR is an adjustable boost converter from Microchip.
