MAX17083 - Step-Down Regulator

Description

The MAX17083 is a fixed-frequency, current-mode, step-down regulator optimized for low-voltage, lowpower applications.

Features

  • dual internal n-channel MOSFET power switches for high efficiency and reduced component count. External Schottky diodes are not required. An integrated boost switch eliminates the need for an external boost diode. The internal 25mΩ low-side power MOSFET easily supports continuous load currents up to 5A. The MAX17083 produces an adjustable 0.75V to 2.7V output voltage from the system’s 3.3V or 5V input supply. This step-down regulator uses a peak current-mode control scheme to eliminate the addit.
