The 1.25 MHz switching frequency is a middle ground: higher than the 400 kHz of the LMS3655MQURNLRQ1 buck (which lacks synchronous rectification), but lower than the 2.1 MHz of the LMR33630APCQRNXRQ1. That means you can use a smaller inductor than a 400 kHz design, but switching losses will be higher than a 2.1 MHz part — a trade-off that matters in thermally constrained enclosures. ## SOT-23-5 Thin package — footprint and handling The SOT-23-5 Thin package is a low-profile, 5-pin surface-mount package. It is compatible with standard SOT-23-5 land patterns.","metaTitle":"TPS62227DDCT TI Buck Regulator 1.2V 400mA SOT-23-5","metaDescription":"Texas Instruments TPS62227DDCT step-down (buck) regulator, fixed 1.2V output, 400mA, 1.25MHz, SOT-23-5 Thin (TSOT-23-5).
