New driver led 2A By Macroblock

MBI6664 is a common-anode buck constant-current LED driver for high power LED stage lighting applications. Hysteretic PFM control with fast response provides high dimming resolution. The LED current can be set by an external resistor. With the integrated MOSFET, MBI6664 can save the PCB size and reduce the total cost effectively. Additionally, MBI6664 offers error flag and complete protection functions, including Under-Voltage Lockout (UVLO), Over Temperature Protection (OTP), Over Current Protection (OCP), output open protection, and output short protection, to protect system or components from being damaged by fault conditions.
