MT7812 Overview
Description
MT7812 is a high precision LED constant current control chip operating at critical conduction mode (CRM) with zero current switched-on and peak current switched-off. It’s mainly targeted for non-isolated buck LED power systems.
Key Features
- Critical Conduction Mode, not sensitive to the inductance
- Up to 95% of efficiency
- Highly accurate constant LED current
- Cycle-by-cycle current limitation
- LED Short Circuit Protection
- LED Over Voltage Protection
- Leading edge blanking technique
- Under-voltage lockout (UVLO) protection
- Over temperature protection
