MAX15040 - Step-Down Regulator

General Description

The MAX15040 high-efficiency switching regulator delivers up to 4A load current at output voltages from 0.6V to (0.9 x VIN).

The device operates from 2.4V to 3.6V, making it ideal for on-board point-of-load and postregulation applications.

Key Features

  • 1MHz fixed-frequency PWM mode operation. The high operating frequency allows for small-size external components. The low-resistance on-chip nMOS switches ensure high efficiency at heavy loads while minimizing critical parasitic inductances, making the layout a much simpler task with respect to discrete solutions. Following a simple layout and footprint ensures first-pass success in new designs. The MAX15040 incorporates a high-bandwidth (> 15MHz) voltage-error amplifier. The voltage-mode control.
