TPS62740 in TI TPS6xxxx Bucks & Boosts Family
The TPS62740 family by Texas Instruments consists of high-efficiency synchronous step-down converters specifically engineered for ultra-low-power applications. Operating with a remarkably low 360 nA quiescent current, these devices are designed to extend battery life in systems powered by Li-ion, Li-primary, or multi-cell alkaline chemistries. The family integrates a load switch and provides 12 pin-selectable output voltages, eliminating the need for external resistor dividers that would otherwise consume power through leakage.
Variants in This Sub-Family
Variants within the TPS6274x sub-family typically differ in their maximum output current ratings, integrated features, and package sizes. For example, while the TPS62740 provides 300mA and an integrated load switch, the TPS62742 offers 400mA, and the TPS62743 is optimized for a smaller footprint with a reduced component count. Some versions also vary in the specific range of pin-selectable output voltages provided to match different MCU or RF transceiver requirements.
