TEA1533AT Converter Offline Flyback Topology , SMPS Controller 25kHz-175kHz 250W

TEA1533AT Converter Offline Flyback Topology 25kHz ~ 175kHz SMPS Controller

GENERAL DESCRIPTION

The GreenChip is the second generation of green Switched Mode Power Supply (SMPS) control ICs operating directly from the rectified universal mains. A high level of integration leads to a cost effective power supply with a very low number of external components. The special built-in green functions allow the efficiency to be optimum at all power levels. This holds for quasi-resonant operation at high power levels, as well as fixed frequency operation with valley switching at medium power levels. At low power (standby) levels, the system operates at a reduced frequency and with valley detection. The proprietary high voltage BCD800 process makes direct start-up possible from the rectified mains voltage in an effective and green way. A second low voltage BICMOS IC is used for accurate, high-speed protection functions and control. Highly efficient and reliable supplies can easily be designed using the GreenChipII control IC.

Koben Electronics was founded in 1995 and is located in the Silicon Valley of China, Shenzhen.

The mission of Koben has always been to provide quality electronics components to manufacturers worldwide. Early on we became a primary conduit for end-of-program and overstock inventory for major distributors such as Future Electronics and contract manufacturers as Flextronics. Koben has since then added sourcing of high quality components from local manufacturers in China.

Koben has always been customer driven rather than opportunity driven. Meaning- we will always choose path that is best for long term relationship with customer over short term view. It is why we have one of the highest customer retention scores of China based distributors.
