آی سی کاهنده ولتاژ PT4115 دارای پکیج SOT89 بسته 5 تایی

The PT4115 IC is a continuous conduction mode inductive step-down converter designed to drive single or multiple series connected LEDs efficiently from a voltage source higher than the total voltage of the LED chain. It operates from an input source between 6V and 30V and provides an externally adjustable output current of up to 1.2A. Depending on the supply voltage and external components, the PT4115 can provide more than 30 watts of output power. This IC includes a power switch and high output current sensing circuitry that uses an external resistor to set the nominal average output current and accepts a dedicated DIM input, either a DC voltage or a wide range of pulse dimming. Applying 0.3V or less to the DIM pin turns off the output and puts the device into low-current standby mode.
