GR1231R Multi-Mode PWM Controller with BNO Protection Features Description Low Start-Up Current (<2uA) The GR1231R is a high performance multi-mode Multi-Mode Operation (QR/CCM) PWM controller for flyback converter. It CCM Heavy Load and Low Line minimizes the components counts and is available QR-Like Operation Medium Load in a tiny SOT-26 package. Those make it an ideal Green mode with Valley Skip at Light Load design for low cost application. It provides functions Burst Mode at No Load of low startup current, green- mode power-saving Accurate Over Current Protection operation, VCC over-voltage protection, brownout Adjustment OVP on QRD Pin protection and QRD pin abnormal conditions sensing to prevent the circuit being damaged from Brown Out Protection Output Short Protection the abnormal conditions.
