DrMOS Integrated Power Stages
DrMOS 5x5 and DrMOS 4x4
DrMOS 4x4 integrated power stage
Infineon's DrMOS integrated power stage, packaged in a very small 4.0x4.0x1.0mm³ PQFN envelope, is offering best-in-class efficiency and very low power loss. Infineon can deliver these benefits by combining its latest generation 25V OptiMOS™ 5 power MOSFET technologies with its proven MOSFET driver silicon. A significant reduction of switching losses enables superior efficiency at higher switching frequencies. Higher switching frequency operation, combined with an extremely small package, enables system designers to save board space and still deliver superior performance.
DrMOS 5x5 integrated power stage
DrMOS 5x5 is an integrated power stage for high performance DC-DC voltage regulation solutions, comprising Infineon’s driver and OptiMOS™ 5 25V power MOSFET technologies in a 5.0x5.0x0.8mm 3 package. It utilizes low-side source-down technique, enabling a big PGND pad for improved thermal coupling to the PCB.
DrMOS integrated power stage
The Intel compliant DrMOS integrated power stage TDA21220 from Infineon incloses a power MOSFET and a driver in one package. DrMOS is optimized for synchronous buck-step down voltage applications.
DrMOS 4x4 efficiency
With the following conditions, DrMOS 4x4 provides more than 94 percent efficiency:
- Vin = 12V
- Vout = 1.8V
- L = 170nH (0.18mΩ)
- Airflow = 300LFM
- 94.2% at 417kHz
- 94.6% at 625kHz
