FP6326 - Synchronous Buck PWM

General Description

The 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.

Key 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.
  • High Output Current.
  • Drives Two Low Cost N-Channel MOSFETs.
  • Fast Transient Response.
  • Simple Single-Loop Control Design ( Voltage-Mode PWM Control).
  • Internal Soft-Start.
  • Over-Current Fault Monitor.

fitipower integrated technology lnc. FP6326/A Synchronous Buck PWM DC-DC Controller Description The 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 operating at fixed 300kHz or 600kHz frequency provides simple, single feedback loop, 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.
