The OC5401 is a single-channel PWM-controlled, high-dimming ratio step-down constant-current driver controller with PWM dimming ratios up to 10,000:1.
The OC5401 supports a 16-60V input voltage range. The OC5401 uses current hysteresis loop control and does not require loop compensation.
The OC5401 can set the LED output current through an external resistor to support a maximum of 5A or more.
The OC5401 supports analog dimming and PWM digital dimming with good dimming performance.
The OC5401 integrates under-voltage protection, over-temperature protection, and other functions.
The OC5401 is available in an ESOP8 package.
