Product details

Description

1 DET This pin is connected to an auxiliary winding of the transformer via resistors of the divider for the following purposes: Generates a ZCD signal once the secondary side switching current falls to zero. Produces an offset voltage to compensate the threshold voltage of the peak current limit to provide a constant power limit.The offset is generated in accordance with the input voltage when PWM signal is enabled. Detects the valley voltage of the s

Features

to enhance the performance of flyback converters. FAN6300A is applied on quasiresonant flyback converters where maximum operating frequency is below 100 kHz. FAN6300H is suitable for high.
frequency operation (up to 190 kHz). A built.
in HV startup circuit can provide more startup current to reduce the startup time of the controller. Once the VDD voltage exceeds the turn.
on threshold voltage, the HV startup function is disabled immediately to reduce power consumption. An in.
