MT8803T0

MT8803T0 is an ultra-low standby power dissipation, non-isolated, BUCK, constant voltage driver, which is suitable for non-isolated power applications with the input range of 85Vac~264Vac.

MT8803T0 incorporates high-voltage power switcher and current sense resistor, excellent constant voltage can be achieved without external compensation capacitor, saving system cost and the BOM size greatly.

MT8803T0 is designed with multi-mode control technology. The chip gets power through both VCC and JFET and can effectively reduce system power consumption.

MT8803T0 provides various protection features to enhance the system reliability, such as cycle-by cycle current limiting (OCP), Over Temperature protection (OTP), over load protection (OLP), short circuit protection (SCP), etc.
