The TPS62675YFDR is a 6 MHz fixed-frequency step-down buck converter from Texas Instruments, delivering a regulated 1.2 V output from an input range of 2.3 V to 4.8 V. The high switching frequency is the key enabler for using a tiny inductor (typically 1 µH or less) and small ceramic capacitors, which together fit the 6-DSBGA package into tight RF or portable-device layouts where board area is the constraint, not the thermal budget.
650 mA output — sizing the load budget
Rated for 650 mA continuous output, this converter suits low-power rails for MCU cores, sensor supplies, or RF transceiver power.
