Infineon – IR3883MTRPBF – 800kHz 3A Integrated POL Voltage Regulator
The IR3883 IR MOSFET IPOL is an easy-to-use, fully integrated and highly efficient monolithic DC-DC regulator. The on-chip PWM controller and MOSFETs make IR3883 a space-efficient solution, providing accurate power delivery. The IR3883 employs an enhanced stability engine that makes it stable with ceramic capacitors without compensation.
