TPSM843321RCJR 30A synchronous power module
The TPSM843321RCJR is a high-performance, 30A synchronous step-down (buck) power module from Texas Instruments, designed for point-of-load (POL) regulation in high-current, space-constrained applications. This fully integrated module in a compact 9mm x 15mm BGA package includes the controller, power MOSFETs, inductor, and input/output capacitors, providing a complete power solution that simplifies design and reduces board area. It operates from a wide input voltage range of 4.5V to 16V and delivers a fixed 3.3V output, making it ideal for converting intermediate bus voltages in advanced computing and communication systems.
The TPSM843321RCJR is primarily targeted at powering high-performance processors, ASICs, FPGAs, and memory arrays in data center servers, telecom infrastructure, and networking equipment. It is also well-suited for industrial automation systems and test/measurement instruments where high current, precise regulation, and a compact footprint are critical requirements.
