SGM3750YTDI6G/TR White LED Driver with PWM Dimming Control

SGM3750YTDI6G/TR is a high efficiency white LED driver with a 650kHz boost converter. With the fixed switching frequency and an internal 40V switch FET,  can use small components. The driver also achieves improved efficiency and reduced output ripple. The SGM3750 integrates LED open protection. It prevents the device from damaging due to the over- voltage during LED open conditions.

The SGM3750 is available in Green TDFN-2×2-6L packages. It operates over an ambient temperature range of -40℃ to +85℃.
