The MAX15021ATI+ is a dual, 4A/2A, 4MHz, step-down DC to DC regulator with tracking/sequencing capability in 28 pin TQFN package. The device operates from 2.5V to 5.5V and each output can be adjusted from 0.6V to the input supply (VAVIN). The MAX15021 delivers up to 4A (regulator 1) and 2A (regulator 2) of output current. It offers the ability to adjust the switching frequency from 500KHz to 4MHz and provides the capability of optimizing the design in terms of size and performance. The MAX15021 utilizes a voltage-mode control scheme with external compensation to provide good noise immunity and maximum flexibility in selecting inductor values and capacitor types. The dual switching regulators operate 180 out of phase, thereby reducing the RMS input ripple current and thus the size of the input bypass capacitor significantly. The MAX15021 offers the ability to track or sequence during power-up and power down operation. When sequencing, it powers up glitch free into a pre-biased output.

• Supply voltage range is 2.5V to 5.5V
• Operating temperature range from -40C to 125C
• Lossless cycle-by-cycle current limit, hiccup-mode output short-circuit protection
• Thermal shutdown
• Shutdown current is 20A
