    Description

    The MAX15106A/MAX15106B/MAX15106C family of high-efficiency, current-mode, synchronous step-down switching regulators with integrated power switches deliver up to 6A of output current. The regulators operate from 2.7V to 5.5V and provide an output voltage from 0.6V up to 95% of the input voltage, making the devices ideal for distributed power systems, portable devices, and preregulation applications.

    The ICs utilize 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 low RDS(ON) integrated switches ensure high efficiency at heavy loads while minimizing critical inductance, making the layout design a much simpler task with respect to discrete solutions. The ICs’ simple layout and footprint assures first-pass success in new designs.

    The regulator features 0.9MHz (MAX15106A), 1.0MHz (MAX15106B), and 1.1MHz (MAX15106C) 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 IC features a capacitor-programmable soft-start to reduce input inrush current. Internal control circuitry ensures safe startup into a prebiased output. Power sequencing is controlled with the enable input and power-good output.

    The IC is available in a 20-bump (4 x 5 array), 2.5mm x 2mm WLP package and is fully specified over the -40°C to +105°C temperature range.
