MT7812 - High Efficiency High Precision Buck Constant Current Driver

Datasheet Summary

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.

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.
