The Texas Instruments TPS62745DSSR is a synchronous step-down buck converter rated for 300 mA continuous output, switching up to 2.5 MHz. The DCS-Control topology combines hysteretic and voltage-mode regulation, giving fast transient response with a small output capacitor — useful when the load current jumps between sleep and active states in a battery-powered sensor node or IoT endpoint.
Programmable output and input range
The input range spans 3.3 V to 10 V, which covers single-cell Li-ion (3.6–4.2 V) and 5 V or 9 V rails. Synchronous rectification eliminates the external Schottky diode, keeping the BOM count low for space-constrained designs.
The 0.50 mm pitch on the 12-WFDFN requires a 4-layer board for proper fan-out and thermal relief; two-layer breaks out only the peripheral pins.
The base product number TPS62745 covers the family; the DSSR suffix denotes the 12-WSON package and tape-and-reel shipping medium.
