TPS51225CRUKR Description

Short technical summary and product information.

The TPS51225CRUKR from Texas Instruments is a cost-effective, dual-synchronous buck controller targeted for notebook system-power supply solutions. This IC provides two buck converters and two integrated linear regulators (LDOs), offering a versatile power management solution.

 

Key electrical specifications include an input voltage range of 5.5 V to 24 V and adjustable output voltages with a ±10% tolerance. It features built-in 100-mA, 5-V and 3.3-V LDOs, a clock output for charge-pump applications, and ±1% reference accuracy. The controller utilizes an adaptive on-time D-CAP mode control architecture with selectable switching frequencies of 300 kHz and 355 kHz, supporting auto-skip light load operation.

 

Designed for reliability, the TPS51225CRUKR includes internal soft-start, output discharge function, separate enable inputs for switchers, and dedicated OC setting terminals. Protection features include OVP/UVP/OCP and non-latch UVLO/OTP. The device operates within a temperature range of -40°C to 85°C.

 

Packaged in a 20-pin WQFN (3x3 mm) with a surface mount type, the TPS51225CRUKR is suitable for space-constrained applications. It comes in a standard package quantity of 3,000 units on tape and reel.
