TPS62353YZGT

Voltage Regulators - DC DC Switching Regulators Overview

The TPS62353YZGT is a high-frequency synchronous step-down DC-DC converter from Texas Instruments, optimized for battery-powered portable applications. It features an input voltage range of 2.7 V to 5.5 V and delivers up to 800 mA output current. The device operates at a fixed switching frequency of 3 MHz, enabling the use of small external components. It offers an adjustable output voltage range from 0.75 V to 1.975 V with precise regulation. The quiescent current is typically 28 µA in active mode, supporting efficient power management. Operating temperatures span from -40°C to +85°C, housed in a compact DSBGA-12 package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'YZGT' corresponds to the DSBGA-12 package and tape-and-reel configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure compatibility with I2C bus voltage levels if used for programming. Check for recent Product Change Notifications (PCNs) regarding pinout or material changes. Validate supply chain authenticity through authorized distributors only.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when space constraints require a small footprint combined with moderate current capability. The 3 MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Consider the I2C interface requirement for dynamic voltage scaling; if fixed output is sufficient, other variants may be more cost-effective. Evaluate thermal performance under maximum load conditions given the small package size.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS6235x family of synchronous step-down converters designed for ultra-low power applications. The family shares common architecture but varies in current rating, switching frequency, and interface options. The TPS62353 specifically targets applications needing 800 mA output with programmable voltage settings via digital interface, distinguishing it from fixed-output counterparts in the same series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include TPS62350, TPS62351, TPS62352, and TPS62354 from the same family, differing primarily in output current ratings. Cross-reference pinouts and electrical characteristics carefully as package variations exist within the series.
