High-current point-of-load power design is becoming more challenging as FPGA, ASIC, processor, telecom and industrial systems require higher current density in smaller PCB areas. Texas Instruments TPSM843B22, TPSM843A26 and TPSM843A22 are synchronous buck power modules designed to simplify high-current rails while reducing the design effort required for discrete converter solutions.

　　The TPSM843B22 is a 20A synchronous buck power module with a 4V to 18V input range and an adjustable output range suitable for low-voltage digital power rails. It integrates key power components, including MOSFETs, inductor and basic passives, into a compact over-molded QFN package. This level of integration helps engineers reduce layout risk, simplify BOM management and accelerate power design validation.

　　For designs with lower current requirements, TPSM843A26 and TPSM843A22 provide 16A and 12A options in the same high-current power module family. These models are useful when engineers want to keep a similar design approach across multiple rails while selecting output current based on actual load requirements.

　　Model comparison:

　　TPSM843B22 – 20A synchronous buck power module

　　·High-current digital rails

　　Selection suggestions:

　　·Choose TPSM843A22 when the rail current is around 12A and compact layout is important.

　　·Choose TPSM843A26 when a 16A rail is required with design margin.

　　·Choose TPSM843B22 when the application needs up to 20A output current.

　　Consider extended temperature versions for harsh or high-reliability environments.
