TPS51225RUKR Description

Short technical summary and product information.

The TPS51225RUKR from Texas Instruments is a cost-effective, dual-synchronous buck controller targeted for notebook system power supply solutions. This integrated circuit provides two synchronous step-down (buck) converters and includes built-in 5-V and 3.3-V LDOs, each capable of supplying 100 mA.

 

Key electrical specifications include an input voltage range of 5.5 V to 24 V and adjustable output voltages with a ±10% tolerance. The device operates with switching frequencies of 300 kHz and 355 kHz, featuring adaptive on-time D-CAP mode control. It also incorporates auto-skip light load operation for efficiency.

 

Packaged in a 20-WQFN (3x3 mm) surface-mount package, the TPS51225RUKR operates within an ambient temperature range of -40°C to 85°C. It offers features such as ±1% reference accuracy, a clock output for charge-pump, internal soft-start, and comprehensive protection mechanisms including OVP/UVP/OCP and non-latch UVLO/OTP.

 

This controller is suitable for applications requiring multiple voltage rails from a single input source, commonly found in portable electronics and system power management.
