OC5265B is a continuous inductor current on-mode step-down LED constant current driver used to drive one or more LED strings. OC5265B operates from 4.8V to 65V and provides adjustable output current up to 1.2A. Depending on the input voltage and external components, the OC5265B can drive LEDs up to tens of watts.
OC5265B Built-in power switch, high-end Shenliu detection circuitry, and dimming foot DIM compatible with PWM and analog dimming. When the DIM pin voltage is lower than 0.3v, the output is turned off and enters the standby state.
OC5265B Built-in over-temperature protection circuit, 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.
OC5265B The patented circuit architecture enables the output current to operate at low dropout voltage without overshoot, improving the LED operating life, OC5265B The patented constant current circuit has excellent load regulation and linear regulation.
OC5265B Adds low-end overcurrent protection to protect the chip from damage in the event of a freewheeling diode short-circuit.
OC5265B is available in a SOT89-5 package.
