FP6188
GENERAL DESCRIPTION
2A, 23V, 340KHz Synchronous Rectified
Step-Down Converter
The FP6188 is a synchronous buck regulator with a built in two 130mΩ MOSFETs. lt achieves
2A continuous output current over a wide input supply range with excellent load and line
regulation. Current mode operation provides fast transient response and eases loop
stabilization. The device includes cycle-by-cycle current limiting and thermal shutdown
protection. The regulator only consumes 23µA supply current in shutdown mode. The FP6188
requires a minimum number of readily available external components to complete a 2A buck
regulator solution.
