General Description:

SGD1011 is a continuous inductor current conduction mode step-down constant current source for driving one or more pieces in series LED. Chip built-in on-resistance of 0.3Ω power switches, the input voltage can be 6V to 36V, and depending on the external device, the chip can drive up to tens of watts of LED, the maximum output current up to 1.2A. SGD1011 has dimming function, through the DIM pin for analog dimming and PWM dimming over a wide range. When VDIM is less than 0.3V, the power switch is turned off, the chip enters a low-power standby state.
