General 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.

Critical conduction mode ensures that the MT7812 turns on the internal power MOSFET when the inductor current reaches zero, reducing the power MOSFET switching loss, the system achieves more than 95% efficiency.

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.
  • SOP8 package MT7812 embedded with internal power MOSFET, simplify the peripheral circuits. Low BOM cost is achieved. MT7812 has.
