To get more students excited about STEM (science, technology, engineering and math) subjects as they head back to school...
Texas Instruments (TI) introduced new 0.2-inch DLP2000 chipset and $99 DLP LightCrafter Display 2000 evaluation module (...
The easy-to-use SWIFT TPSM84A21 and TPSM84A22 DC/DC modules integrate power MOSFETs, shielded inductors, input and output capacitors, and passives into a tiny, low profile footprint. In addition, it provides industry-leading performance, with as little as 1 percent overshoot in transient conditions without special magnetics or additional capacitors.
By using the step-down power module together with TI's WEBENCH Power Designer, engineers can get their space-constrained point-of-load (POL) telecom, networking, and test and measurement power-supply designs to market faster. TI will demonstrate the TPSM84A22 module in its booth (No. 701) at the Applied Power Electronics Conference (APEC), March 27-29 in Tampa, Florida.
Unlike other 10-A step-down modules available today, the highly integrated TPSM84A21 and TPSM84A22 require just one external voltage-setting resistor for a complete 12-V step-down power solution. For an application such as powering tightly regulated field-programmable gate array (FPGA) rails, a typical 10-A module would require up to 16 external capacitors.
In comparison, the TPSM84A21 provides ultra-low output ripple due to the very high 4-MHz switching frequency and integrated 185 microfarads of output capacitance, which maintains regulation accuracy without any external capacitors.
