Texas Instruments LM3646YFQR is a high-efficiency, dual-output LED driver with I2C dimming capabilities, designed for demanding applications. This DC-DC boost regulator features two channels, each capable of delivering up to 1.5A for high-current flash applications. The device operates with an input voltage range of 2.7V to 5.5V and utilizes a 4MHz switching frequency for compact inductor selection. Its 20-DSBGA package (2.04x1.78) facilitates miniaturization in space-constrained designs. The LM3646YFQR integrates internal switches, simplifying external component count. This component is widely utilized in mobile devices and camera flash systems.
