Analog dimming and wide range
product description
PT4115 is a continuous inductor current conduction mode reducing
Voltage constant current source, used to drive one or more LEDs in series.
PT4115 input voltage range from 6V to 30V, output current
Adjustable, up to 1.2A. According to different input voltages and
external device, the PT4115 can drive up to tens of watts
LED. PT4115 has a built-in power switch and adopts high-end current sampling
This sets the average LED current through the DIM pin to accept
PWM dimming. When DIM's
When the voltage is lower than 0.3V, the power switch is turned off and PT4115 enters
Enter a very low operating current standby state.
