Présentation
Description
Key features include its high efficiency, typically above 90%, low quiescent current, and capability to start up with a low input voltage. It operates in a pulse frequency modulation (PFM) mode at light loads and switches to a pulse width modulation (PWM) mode at higher loads, optimizing efficiency across various conditions. The TPS61201DRCR comes in a small, thermally enhanced 10-pin SON package, making it suitable for compact designs.
Common applications include portable electronics, personal medical devices, and other low-power consumer products. Its robust design ensures reliable performance in scenarios requiring efficient power conversion from single-cell battery sources.
