We are a 10 years around integrate circuit chip selling company. We are a agent for several biggest IC project company. Would love to offer technical service. Talk with us, we would offer the exact item to replace the model you need. 

The OC6781 is a high-efficiency, high-precision boost converter
Laminated LED Constant Current Driver Control Chip.  

The OC6781 features a built-in high-precision error amplifier and oscillation
Oscillator, constant current drive circuit, etc., particularly suitable for high power
Multiple high-brightness LED string constant current drivers.  
The OC6781 employs fixed-frequency PWM control
The method allows the operating frequency to be set via an external resistor.  
The OC6781 features built-in frequency compensation, eliminating the need for external compensation
Compensation, application design is simple and reduces peripheral components.  
The OC6781 integrates soft start and output over
```Overvoltage protection, cycle-by-cycle current limiting protection, and overtemperature protection```
The path reduces peripheral components and enhances system reliability.
