Product Summary
The R2A20117 is a Renesas PFC Control IC for Digital-TV. The R2A20117 is used in product ranges such as HD digital TVs, PC monitors, and plasma display panel (PDP) TVs. The market for these types of products has grown substantially in recent years, due to increasing availability of digital services and digital media content. The screen size and precision of TVs and monitors using FPDs are constantly increasing and need to be eco-friendly, as they are typically in use for several hours every day.
Parametrics
R2A20117 absolute maximum ratings: (1)Critical conduction, interleaving; enhanced protection; (2)Target power range is over 300V; (3)Realize high reliability on PFC block by R2A20111 and coordinate next stage by P.G.; (4)Realize small transformer and high efficiency by using half bridge topology by HA16150.
Features
R2A20117 features: (1) Continuous conduction mode is suitable for the system with large and high frequency variation of current; (2) Easy design by separate current terminal; (3) Hold function countermeasure to AC temporary blackout. It is possible to set no soft start time by chip capacitor; (4) Feed back loop detector; (5) Soft start period become short by quick soft start function; (6) Improve the load regulation by gm Amp at feed back Amp.
