MT7752
MT7752 is TRIAC Dimmable Constant Current LED Driver manufactured by Maxic Technology.
DESCRIPTION
FEATURES
MT7752 is a high current precision TRIAC dimmable LED driver. It’s mainly applied for non-isolated LED power systems. MT7752 supports high power factor application. Power Factor (PF) can reach 0.8 or higher.
MT7752 applies to Buck-Boost and Boost topology. It integrates proprietary linear pensation circuit, to achieve excellent constant current performance and wide range dimmer patibility.
MT7752 integrates high voltage supply circuit, which saves the VCC capacitor and start-up resistor. It also integrates a 600V MOSFET, which greatly reduces BOM cost and peripheral ponents.
Critical conduction mode ensures that the MT7752 turns the internal MOSFET on, when the inductor current reaches zero, reducing the power MOSFET switching loss, and achieving more than 90% efficiency. And the system is insensitive to the inductance changes.
MT7752 provides various protections, such as...
