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

Love this. Turns my iPad into a mini laptop
Size: For iPad 10th / A16 (11th), Color: Black
I love this wireless keyboard case and mouse combo for my iPad. It helped me turn my iPad into a little laptop and it is super helpful. It's light weight and functions well. Has light up keys and they can change colors. Has a spot for a pen which is nice.

Good if you don't need a trackpad
Size: For iPad 10th / A16 (11th), Color: Light Pink
The keyboard is nice and tactile, the connection for both mouse and keyboard was seamless. Good product but I am reconsidering because I didn't realize how much I'd miss a trackpad.
