Description

MAXIM INTEGRATED PRODUCTS MAX15021ATI+ DC/DC Switching Regulator, Synchronous, Dual, 2.5 V to 5.5 V in, 5.5 V/4 A out, 4 MHz, TQFN-28The 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

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 -40°C to 125°C
  • Lossless cycle-by-cycle current limit, hiccup-mode output short-circuit protection
  • Thermal shutdown
  • Shutdown current is 20µA

Lightweight, Easy to Install, and Holds Up Well
Size: Full, Color: Black
This bed skirt has been a great purchase. It’s very lightweight, which actually made it super easy to put on the bed without a struggle. Once in place, it looks nice and does exactly what it’s supposed to do. It’s also held up well to my almost-teenager being a little reckless at times, no tearing or issues so far. For the price, it’s definitely a good value. Overall, simple, functional, and worth it if you need a clean finished look for your bed.

Great for the price
Size: Full, Color: Bright White
Great for the price. The fabric is thin and not made well but for the price it’ll do. Must iron it so that it lays correctly but I figured I’d have to.
