Dual-rail power from a single inductor
The Texas Instruments TPS61100PWR integrates a synchronous step-up (boost) converter and a linear LDO regulator in one 20-TSSOP package. Output 2 is the LDO: adjustable from 0.9 V to 3.6 V at 500 mA. The two rails let one IC power both the main load and a lower-voltage analog or logic rail without a second switcher.
500 kHz switching — inductor sizing trade-off
The boost converter switches at 500 kHz.
Temperature range and board environment
The 20-TSSOP body (4.40 mm width) is a surface-mount footprint that reflows without special handling.
