Low startup current and low operating current contribute to a reliable power on startup and low standby loss design with SCM1733ASA. SCM1733ASA offers complete protection coverage with automatic self recovery feature including Cycle-by-Cycle current limiting(OCP), over load protection(OLP),VDD under voltage lockout (UVLO),over temperature protection (OTP),and over voltage protection (OVP).Excellent EMI performance is achieved with internal frequency jitter technique and soft switching control at the totem pole gate drive output. The tone energy at below 22KHz is minimized in the design and audio noise is eliminated. SCM1733ASA is offered in SOP-8 package.
