LED driver chip SGM3750YTDI6G/TR for U110 location of Antminer S17

With a 40V rated integrated switch FET, the SGM3750YTDI6G/TR is a 650kHz fixed switching frequency boost converter that drives LEDs in series, improves conversion efficiency, and allows for the use of small external components. In PWM mode, the SGM3750 integrates an open LED Protect. It prevents the device from being damaged by overvoltage in an open LED condition. There will be no burst of LED current. Therefore, it will not create audible noise on the output capacitor. For maximum protection, the device has an integrated open LED protection feature that disables the SGM3750 to prevent the output voltage from exceeding the IC's absolute maximum voltage rating during an open LED condition.
