Feedback loop is grounded. The voltage rises to an abnormally high level, which breaks the capacitor.Disconnection of the feed-back loop is detected, and power output stops! Prevents destruction of the discrete capacitor and power MOS! > 2009. RenesasTechnology Corp., All rights reserved.RenesasPower Supply and Charger ICs General Presentation size="-1">

1. Concept of critical mode interleaving by the R2A20112 2. Main purpose of interleaving PFC Reduction of input noise3. Effectirenessof R2A20112/realization of slim size4. Introduction of slimlineboard 5. Prevention of overvoltagesby using dynamic overvoltage protection, which controls audible noise without allowingthe output voltage to exceed the rated value (in consideration of PFC control)6. Critical mode single-chip PFC (R2A20113) for the lowoutput range > 1-8 2009. RenesasTechnology Corp., All rights reserved.RenesasPower Supply and Charger ICs General Presentation size="-2">

AC inputOutput voltage Hold counter > Even where the power supply has become unstable, IC operationis maintained for a certain period of time by hold-mode operation, so that recovery is faster. Hold timer (adjustable) FET out(HA16174)FET out(without hold function) > Remarks : The above function is only available for a limited time after supply of the correct Vccto the IC stops. If the AC brownout is longer than the hold time, the HA16174 will stop operating, making this function ineffectual. 1-17 A period over which the user does not wish to have soft-start operation after a sudden...
