ECOMOS TM high efficiency MOSFETs for DC/DC power supplies
Overview
|
The increasing performance of PCs and servers increases power consumption, resulting in higher temperatures and decreased battery life. In answer to this ROHM
has developed the ECOMOSTM RMW series of high efficiency, low power consumption MOSFETs optimized for high performance DC/DC power supply circuits. |
 |
Key Feature 1 : Low ON resistance + low capacitance
|
An original low-capacitance structure minimizes switching loss at the high side of DC/DC synchronous rectification circuits while simultaneously ensuring low ON resistance characteristics for decreased conduction loss through the low side. Qgd is 40% higher than competitor models. |
 |
Key Feature 2 : Industry's highest efficiency
|
ROHM's ultra-high efficiency characteristics contribute to lower power consumption in DC/DC power supply circuits, while high frequency synchronous rectification operation
decreases the size of peripheral circuitry. |
 |
Key Feature 3 : High heat dissipation PSOP8 package
|
A low capacitance, low ON resistance element is encapsulated in a high heat dissipation PSOP8 package
(5.0 to 6.0 to 0.9mm) for greater power- and current-handling capability. |

Applications
| PCs (notebooks, tablets, desktop), servers, network devices, gaming systems, power supply modules, and more |
