1 / 31 page General Description The MAX15003 is a triple-output, pulse-width-modulat- ed (PWM), step-down DC-DC controller with tracking and sequencing capability. The device operates over the input voltage range of 5.5V to 23V or 5V ±10%. Each PWM controller provides an adjustable output down to 0.6V and delivers up to 15A for each output with excellent load and line regulation. The MAX15003 is optimized for high-performance, small-size power management solutions. The options of coincident tracking, ratiometric tracking, and output sequencing allow the tailoring of the power- up/power-down sequence depending on the system requirements. Each of the MAX15003 PWM sections uti- lizes a voltage-mode control scheme with external com- pensation allowing for good noise immunity and maximum flexibility with a wide selection of inductor val- ues and capacitor types. Each PWM section operates at the same, fixed switching frequency that is program- mable from 200kHz to 2.2MHz and can be synchro- nized to an external clock signal using the SYNC input. Each converter operating at up to 2.2MHz with 120° out-of-phase, increases the input capacitor ripple fre- quency up to 6.6MHz, thereby reducing the RMS input ripple current and the size of the input bypass capaci- tor requirement significantly. The MAX15003 includes internal input undervoltage lockout with hysteresis, digital soft-start/soft-stop for glitch-free power-up and power-down of each convert- er. The power-on reset (RESET) with an adjustable timeout period monitors all three outputs and provides a RESET signal to the processor when all outputs are within regulation. Protection features include lossless valley-mode current limit and hiccup mode output short-circuit protection. The MAX15003 is available in a space-saving, 7mm x 7mm, 48-pin TQFN-EP package and is specified for operation over the -40°C to +125°C automotive temper- ature range. See the MAX15002 data sheet for a dual version of the MAX15003.
