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

So far, so good!
Size: 1.7 Ounce (Pack of 1)
It rubs in clear very nicely and doesn’t feel greasy or heavy on my skin.

Nontoxic sunscreen
Size: 1.7 Fl Oz (Pack of 2)
Excellent sunscreen! Nontoxic and gentle. I have sensitive skin and chemical sunscreens can irritate my skin, so I switched to this one. It has a creamy feel, but doesn’t make your skin look or feel oily. I have dry-normal skin, for reference. It initially has a bit of a white cast, but once rubbed in you don’t notice it.

Good sunscreen, but the shade didn’t work for me
Color: Medium
I bought the Colorescience Flex in Medium because I had seen great reviews and liked the idea of a tinted mineral sunscreen. The formula itself felt really high quality and it did provide good sun protection, but the shade didn’t end up working for my skin tone.
✔️ What I liked:
- Great daily mineral sun protection.
- Lightweight texture and easy to apply.
- Didn’t irritate my skin or cause breakouts.
- Nice natural finish at first.
❌ What I didn’t like:
- On my skin, the Medium shade looked orange.
- The color didn’t blend well with my undertone.
- I had to work it in quite a bit to avoid a noticeable line with my neck.
I think the formula is really good, but the shade selection definitely requires care. In my case, it just wasn’t the right match

Finally found my perfect match!! In foundation!
Color: Medium, Color: Medium
I’ve used many high-end foundations over the years, but Colorescience has become my everyday favorite. It feels incredibly lightweight on the skin and provides a natural, healthy-looking finish that doesn’t feel heavy or cakey.
The added SPF is a huge bonus and makes my morning routine so much easier. I also love how perfectly it matches my skin tone, it blends seamlessly and looks like my skin, just more even and polished.
If you prefer a natural, lightweight foundation with the added benefit of sun protection, this one is definitely worth trying.
