Infineon Technologies AG (Munich, Germany) introduced its TDA21201 single-package, integrated switch that allows designers of switching power supplies to reduce system costs by as much as 50 percent and reduce space. The TDA21201 component is suitable for personal computers, notebook computers and other portable and space-constrained electronic devices.
The TDA21201 devices convert a 12V input into levels of less than 3.5V to power the variety of components within personal computers, peripherals and other electronic systems. The TDA21201 achieves efficiencies of over 80 percent at a 200kHz switching frequency for currents of 20A. The drive capability of the gate driver allows the TDA21201 to be operated in the frequency range of 100kHz to 500kHz. Over-temperature protection shuts down both MOSFETs when the temperature is above 150 degrees C.
The TDA21201 is available now in industry-standard TO220-7-128 D2-PAK, TO220-7-3 straight-lead and TO220-7-230 staggered-lead packages. It is priced at $1.50 in 10,000-piece quantities.
