This shrinks the total converter footprint compared to a 1 MHz or 500 kHz design, at the cost of slightly higher switching losses in the internal FETs — a trade-off that favours space-constrained, moderate-load applications. ## Fixed 2.85 V output — one less resistor divider The output is factory-set to 2.85 V (fixed), so no external feedback resistor network is required. That saves two resistors and one feedback-node capacitor from the BOM, and eliminates the tolerance stack of the divider from the output accuracy budget. ## 6-DSBGA package — layout and assembly considerations The 6-bump DSBGA (0.4 mm pitch, approximately 1.2 mm × 0.9 mm body) requires a fine-pitch stencil and a reflow profile tuned for lead-free solder. The small thermal mass means the part heats up quickly — the recommended land pattern and solder paste coverage are detailed in the datasheet layout section. ## Operating temperature range and environment The synchronous rectifier (integrated) improves efficiency at light loads, which helps keep the die temperature down in a sealed enclosure.","metaTitle":"TPS62693YFDR Step-Down Regulator, 3 MHz, 800 mA","metaDescription":"Texas Instruments TPS62693YFDR: 3 MHz synchronous buck regulator, 800 mA output, fixed 2.85 V.
