Sanyo EP91G Benutzerhandbuch

Contemporary electronic equipment requires a wide range of high-level technologies to remain viable in today's 
competitive market. For example, cell phones require technologies that achieve stable operation at low input 
voltages, improved efficiency, and further miniaturization in the power supply system. Similarly, digital home 
appliances not only requires low-power/low-voltage operation and improved efficiency, but also low power 
consumption in standby mode to meet energy usage requirements and the ability to meet high-frequency radiation 
standards.
We at SANYO Semiconductor makes a point of grasping these needs as early as possible and developing ICs 
contributing to achieve improved system development and high level of integration based on our rich experience in 
general-purpose product technologies.
