Low-Voltage, Internal Switch, Step-Down
Regulator
General Description
The MAX17083 is a fixed-frequency, current-mode, step-down
regulator optimized for low-voltage, lowpower applications.
This
regulator 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...
