PT4115 application circuit

The PT4115 is a continuous inductor current conduction mode buck constant current source for driving one or more series LEDs. The PT4115 has an input voltage range of 6 volts to 30 volts and an adjustable output current of up to 1.2 amps. Depending on the input voltage and external components, the PT4115 can drive up to tens of watts of LEDs. The PT4115 has a built-in power switch that uses high-side current sampling to set the LED flat current and accepts analog dimming and a wide range of PWM dimming through the DIM pin. When the voltage of the DIM is lower than 0.3 volts, the power switch is turned off, and the PT4115 enters a standby state with extremely low operating current.

The PT4115 is available in SOT89-5 and ESOP8 packages.
