PT4115B89E 30V 1.2A STEP-DOWN HIGH BRIGHTNESS LED DRIVER IC

PT4115 is a inductor buck converter of continuous conduction mode, used to drive one or multiple series connected LED design, one voltage is more efficient than whole LED voltage chain. The device is between the 6V and 30V to input power, and provided with an external adjustable output current up to 1.2A.

In the power supply voltage and the external components of the different, PT4115 offers more than 30 watts of output power. The PT4115 includes power switch and a high output current detection circuit, and used for an external resistor to set the nominal average output current, and a dedicated DIM input, no matter what DC voltage or pulse light modulation range.

Applying a series of voltage of 0.3V or lower DIM turns off the output pins, and switch a low current standby equipment. The PT4115 is available in SOT89 5 package Features: v Simple low parts count v Wide input voltage range: 8V to 30V v Up to 1.2A output current v Single needle opening / closing switch and the use of DC voltage or PWM brightness to control v Up to 1MHz switch frequency v Typical 5% output current accuracy v The inner open LED protection v High efficiency (up to 97%).V High side current detection v The hysteresis control: no compensation v Adjustable constant current of LED Application:Low voltage halogen replace light-emitting diode Automotive lighting Low voltage industry lighting Days preparing lighting The luminous sign The lighting is suitable for SELV The backlight of LCD TV.
