The OC5260 is a step-down LED constant current driver with built-in power MOS continuous inductor current conduction mode for driving one or more LED strings. The OC5260 operates from 5.5V to 60V and provides adjustable output current with a maximum output of 2.5A.
The OC5260 has a built-in power switch with high-side current-sensing circuitry, and a dimming pin ADJ that is compatible with PWM and analog dimming. When the ADJ pin voltage is lower than 0.3V, the output is turned off and enters the standby state. In addition, the DIM pin can be controlled by a digital dimming foot.
The OC5260 has a built-in over-temperature protection circuit, and when the chip reaches the over-temperature protection point and enters the over-temperature protection mode, the output current gradually decreases to improve system reliability.
The OC5260 features a built-in LDO with an output voltage of 5.5V and a maximum current output of 5mA.
The OC5260 uses a patented circuit architecture to ensure that the output current is free of overshoot when operating at low dropout voltage, improving the life of the LED, and the OC5260 uses a patented constant current circuit with excellent load regulation and linear regulation.
The OC5260 is available in an ESOP8 package.
