Overview
The LM3407MY is a LED Driver made by Texas Instruments in a HVSSOP-8-EP-0.65mm package with 9 pins. -40℃~+125℃ 1 10% 100mV~900mV 300kHz~1MHz 350mA 4.5V~30V Buck Built-in DC-DC PWM Under Voltage Protection、Over-Temperature Protection (OTP) HVSSOP-8-EP-0.65mm LED Drivers ROHS.
PCBKit's library has its KiCad symbol (Regulator_Switching:LM3407MY, from KiCad's library) and its footprint (Package_SO:MSOP-8-1EP_3x3mm_P0.65mm_EP1.73x1.85mm, from KiCad's library), ready for a KiCad board. 101 are in stock at JLCPCB (part C701830). 2 open-source boards in 2 repositories on GitHub use it.
