TPS54A20RNJT Description

Short technical summary and product information.

The TPS54A20RNJT from Texas Instruments is a high-performance, two-phase synchronous series capacitor buck converter. It is designed for applications requiring efficient step-down voltage conversion, operating with an input voltage range of 8-V to 14-V and capable of delivering up to 10-A of output current.

 

This converter features an adjustable output voltage range from 0.51-V to 2-V, with a feedback reference voltage accuracy of ±0.5%. It offers a selectable switching frequency between 2-MHz and 5-MHz per phase, a minimum on-time of 14-ns, and input overvoltage lockout for surge protection up to 17-V. The device includes adjustable current limit with auto-restart and synchronizes to an external clock.

 

Packaged in a 20-VQFN-HR (4x3.5) surface-mount package, the TPS54A20RNJT operates within a temperature range of -40°C to 125°C (TJ). It is suitable for various power management applications where space and efficiency are critical.
