The 1.2 MHz switching frequency lets you use a 2.2 µH to 4.7 µH inductor and a 10 µF ceramic output cap — small enough for a compact SOT-23-6 layout. ## 500 mA switch current — sizing the output power In a typical 3.3 V output from a 3.0 V input, that delivers roughly 300–350 mA to the load before the switch cycle-by-cycle current limit engages — enough to power a small sensor node, a Bluetooth module, or a CODEC. The synchronous rectifier replaces the usual Schottky output diode with a low-side FET, which lifts efficiency into the mid-80s at light loads and eliminates the diode's forward-voltage drop at higher output currents. ## SOT-23-6 package — layout and thermal notes The TPS61071DDCR comes in a thin SOT-23-6 (TSOT-23-6) package with a 0.95 mm pitch. Route the input and output capacitors as close as possible to the IC pins; the 1.2 MHz switching edges couple into the feedback trace if the layout is loose.","metaTitle":"TPS61071DDCR Boost Converter, 0.9V-5.5V Input, 500mA Switch","metaDescription":"Texas Instruments TPS61071DDCR step-up DC-DC converter.
