TPS54218RTER – 2A, 6V Synchronous Step-Down SWIFT Converter IC

The TPS54218RTER is a compact, high-efficiency 2A synchronous step-down (buck) DC-DC converter from Texas Instruments’ SWIFT family, designed to deliver precise voltage regulation in small, thermally efficient designs. Operating from an input voltage range of 2.95V to 6V, the device integrates both high-side and low-side 30mΩ MOSFETs, significantly reducing external component count while maintaining excellent efficiency. With its current-mode control architecture, the TPS54218 ensures fast transient response and stable operation across varying loads. The device supports switching frequencies up to 2MHz, minimizing the size of external inductors and capacitors for compact designs. Featuring a +-1% voltage reference (VREF) over temperature, it provides accurate and reliable output voltage regulation, ideal for precision power applications. Efficiency is further enhanced by a low 350uA typical supply current, while the shutdown current of 2uA enables low-power standby operation when disabled via the EN pin. Additional features include programmable undervoltage lockout (UVLO), soft-start control, and a power-good (PG) indicator that signals when the output is within 93%–107% of nominal voltage. Comprehensive protection mechanisms such as frequency foldback, cycle-by-cycle current limit, and thermal shutdown ensure safe operation under fault conditions.
