PL82052 - 3.5A Monolithic Step-Down Switching Regulator

General Description

The PL82052 is a monolithicsynchronous buck regulator with wide operating input voltage range from 4.6 to 33V.

Current mode control with internal slope compensation is implemented to reduce component count.

Key Features

  • 3.5A continuous output current capability.
  • 4.6V to 33V wide operating input range.
  • Integrated 40V, 80mΩ high side and 40V, 50mΩ low side power MOSFET switches.
  • Up to 97% efficiency.
  • Soft-Start time can be adjusted by user to limit inrush current at turn-on.
  • Adjustable 80-kHz to 2-MHz Switching Frequency Set by an External Resistor (Leave pin ROSC floating. Set frequency to 160 kHz, Connect ROSC to GND, Set frequency to 80 kHz).
  • Pulse Skipping Mode to Achieve H.
