DC DC Switching Controllers Procurement Notes

Verify the specific ordering suffix and tape-and-reel quantity requirements directly with Microchip Technology or authorized distributors before placing orders. Confirm that the TQFN-20 package dimensions align with your PCB footprint design. Ensure that the 3.3V/5V supply input constraints are compatible with your system's power rails. Check for any recent product change notices regarding assembly sites or testing procedures to maintain supply chain consistency.

DC DC Switching Controllers Selection Notes

Select this component when designing systems that require high current capability up to 40A with precise current mode control. The wide switching frequency range allows optimization for both efficiency and transient response. Consider the 50% maximum duty cycle limitation when selecting input-to-output voltage ratios. The 3.3V logic compatibility simplifies integration with standard microcontrollers or DSPs for digital control loops.
