The MAX15053 high-efficiency, current-mode, synchronous step-down switching regulator with integrated power switches delivers up to 2A of output current. The device operates from 2.7V to 5.5V and provides an output voltage from 0.6V up to 94% of the input voltage, making the device ideal for distributed power systems, portable devices, and preregulation applications.

The MAX15053 utilizes a current-mode control architecture with a high gain transconductance error amplifier. The current-mode control architecture facilitates easy compensation design and ensures cycle-by-cycle current limit with fast response to line and load transients.

The MAX15053 offers selectable skip-mode functionality to reduce current consumption and achieve a higher efficiency at light output load. The low RDS(ON) integrated switches ensure high efficiency at heavy loads while minimizing critical inductances, making the layout design a much simpler task with respect to discrete solutions. Utilizing a simple layout and footprint assures first-pass success in new designs.

The MAX15053 features a 1MHz, factory-trimmed, fixed-frequency PWM mode operation. The high switching frequency, along with the PWM current-mode architecture, allows for a compact, all-ceramic capacitor design.

The MAX15053 offers a capacitor-programmable soft-start reducing inrush current, startup into PREBIAS operations, and a PGOOD open-drain output that can be used as an interrupt and for power sequencing.

The MAX15053 is available in a 9-bump (3 x 3 array), 1.5mm x 1.5mm WLP package and is specified over the -40°C to +85°C temperature range.
