For a 12 V input to 3.3 V output at 1.5 A, the power dissipation is roughly 1.3 W — budget a 1-inch-square copper pour on the bottom layer with thermal vias to keep the junction below 125°C.","metaTitle":"TPS62111RSARG4 3.3V Step-Down Buck Converter, 1.5A, 1MHz","metaDescription":"Texas Instruments TPS62111RSARG4 is a 3.3V fixed-output synchronous buck converter rated 1.5A at 1MHz switching.
