The OB3338CCPA is an LED driver manufactured by On-Bright. It is an 8-pin SOP (Small Outline Package) package that is RoHS (Restriction of Hazardous Substances) compliant. The OB3338CCPA preset constant current PWM LED driver is optimized for step-down topology, allowing it to efficiently drive LEDs with low quiescent current. This makes it suitable for a range of applications including LED lighting, automotive lighting, LED displays, and more. It has a wide 4.0V to 40V input voltage range. It has a maximum 450kHz switching frequency, allowing it to support a high PWM dimming frequency and constant frequency control. It comes with a wide adjustable output current range of 5mA to 500mA and its integrated over-temperature protection prevents circuit working beyond its maximum junction temperature.
