TPS62122DRVR 15V, 75mA High-Efficiency Buck Converter
The TPS62122DRVR is a compact, high-efficiency synchronous step-down (buck) DC-DC converter from Texas Instruments, designed for low-power, battery-operated, and energy-harvesting applications. Operating over a wide input voltage range of 2V to 15V, it supports diverse power sources including single-cell Li-ion batteries, 9V/12V wall adapters, and industrial bus lines. This device delivers a precisely adjustable output voltage from 1.2V to 5.5V, with a maximum load current of 75mA, achieving peak efficiency of up to 96%. Leveraging TI's advanced DCS-Control topology and a fixed 800kHz switching frequency, it ensures fast transient response, low output ripple, and stable regulation across light to full loads. It features an ultra-low quiescent current of 11µA in Power Save Mode, significantly extending battery life in standby conditions. Encased in a tiny 6-pin, 2mm × 2mm WSON (DRV) package with an exposed thermal pad, it offers excellent thermal dissipation and is optimized for space-constrained PCBs. The device includes internal soft-start, 100% maximum duty cycle operation for low dropout, and is fully RoHS-compliant, operating reliably over the industrial temperature range of -40°C to +85°C.
