TPS622314TDRYRQ1

The TPS622314TDRYRQ1 from Texas Instruments is a high-frequency, synchronous step-down DC-DC converter suitable for space-constrained automotive and industrial applications. This device supports an output current of up to 500mA and operates with an input voltage range from 2.05V to 6V, making it compatible with various power sources including Li-Ion batteries.

Featuring a fixed 1.5V output voltage, the TPS622314TDRYRQ1 boasts a switching frequency of up to 3.8MHz, allowing for the use of small external components like chip inductors and capacitors. It achieves high efficiency of up to 94% and offers excellent AC and transient load regulation. The converter operates in PWM mode at medium to heavy loads and automatically enters Power Save Mode at light loads, with a typical quiescent current of 22µA.

The device is housed in a compact 1x1.5mm 6-SON package, contributing to a minimum solution size of 12mm². It supports a maximum solution height of 0.6mm and includes a soft-start feature with a typical start-up time of 100µs. The TPS622314TDRYRQ1 is qualified for automotive applications.

Key electrical characteristics include a 2.05V to 6V input voltage range, a fixed 1.5V output voltage, and a maximum output current of 500mA. The operating temperature range is -40°C to 105°C. The package is a 6-UFDFN or 6-SON, surface-mount type, supplied on tape and reel in quantities of 5000.
