General Description
The MAX15048/MAX15049 are triple-output pulse-width modulated (PWM), step-down, DC-DC controllers with tracking (MAX15048) and sequencing (MAX15049) options. The devices operate over the 4.7V to 23V inputvoltage range. Each PWM controller provides an adjustable output down to 0.6V and delivers up to 15A of load current with excellent load and line regulation. The MAX15049 can start into prebiased outputs. The MAX15048/MAX15049 are optimized for high-performance, small-size power management solutions.
