The Texas Instruments LM3668SDX-4550-NOPB is a highly efficient buck-boost switching regulator IC. This device offers programmable positive output voltages of 4.5V and 5V from a single output, capable of delivering up to 1A. Operating with an input voltage range of 2.5V to 5.5V, the LM3668SDX-4550-NOPB utilizes a 2.2MHz switching frequency for compact inductor and capacitor selection. Its advanced buck-boost topology and synchronous rectification ensure optimal power conversion efficiency. Packaged in a 12-WSON (3x3) with an exposed pad, this surface-mount component is ideal for applications in portable electronics, mobile devices, and other power-sensitive systems. The device operates within an ambient temperature range of -40°C to 85°C.
