Recently announced in launched a set of 12 v, 10. A, 4 MHZ step-down power supply module, compared with the existing 10 a power supply module solutions market, the volume of power management solutions can be decreased 20%. SWIFT TPSM84A21 and TPSM84A22 DC/DC module is easy to use, and will power MOSFET, isolation inductor, the input and output capacitance and passive components integrated in thin encapsulation. In addition, it also has the industry leading performance, without using special magnetic components or extra capacitance, can be in transient condition only 1% overshoot. By using a step-down power module and TI WEBENCH ® power supply design tool, engineers can speed up the loading point limited space such as communications, networking, test and measurement listed speed type power supply design. Unlike other 10 a step-down module on the market, to complete the 12 v step-down power solutions, highly integrated TPSM84A21 and TPSM84A22 can set the voltage with a resistor. For power supply accurate adjustment of field programmable gate array (fpga) power supply rails applications, such as 10 a module of typical requirements up to 16 external capacitance. Because TPSM84A21, by contrast, have extremely high 4 MHZ switch frequency, and integrates the micro ferrari 185 output capacitance, it can provide low output ripple, can achieve precise without external capacitance voltage stabilizing ability.

TPSM84A21 and TPSM84A22 key features and advantages:

Small volume: a 9 mm * 15 mm module and an external voltage setting resistor is composed of a complete solution, the total footprint is only 11 mm * 15 mm.

Thin: 2.3 mm high, small size, light weight, less material, the overall solution can be installed in the back of the printed circuit board.

Best transient performance: 4 MHZ switch frequency, can achieve without external capacitance overshoot of plus or minus 1%.

Design is simple: integration input and output capacitor, the design process without considering compensation or magnetic circuit selection. Use WEBENCH power supply design tool, need a voltage set resistor can quickly create a complete 12 v, 10 a DC/DC buck solution.
