天玉LED驱动芯片FP6326

DescriptionThe FP6326/A is designed to drive two N-channel MOSFETs in a synchronous rectified buck topology. It provides the output adjustment, internal soft-start, frequency compensation networks, monitoring and protection functions into a single package. The IC which operates at fixed 300kHz or 600kHz frequency provides simple, single feedback loop, and voltage mode control with fast transient response. The resulting PWM duty ratio ranges from 0-100%. The FP6326/A features over current protection. The output current is monitored by sensing the voltage drop across the RDS-ON of the low side MOSFET which eliminates the need for a current sensing resistor. This device is available in SOP-8 package. Features● Operates from +5V or +12V
