Attached Qualification Report. Provided estimated first ship date to be on October 31, 2025.
Description of Change: Qualification of Microchip Technology Colorado ? Fab 5 (MCSO) as a new fabrication location for multiple device families available in various packages.Reason for Change: To improve manufacturability and on time delivery performance by qualifying a new fabrication location (MCSO - FAB 5), which is a Microchip-owned facility that offers significant expansion potential to better meet future client demand. *Note: The attached file called Tempe_Fab2_IATF_Decertification is for the manufacturing site deactivation of Microchip Technology Tempe ? Fab 2 (TMGR), contact your local Microchip sales office for inquiries.Estimated Qualification Completion Date: September 2025Pre and Post Summary Changes:? Pre Change: Fabrication Site = Microchip Technology Tempe ? Fab 2 (TMGR), Wafer Size = 8"? Post Change: Fabrication Site = Microchip Technology Colorado(MCSO), Wafer Size = 6"

Features & Applications
The MIC2172YM TR are complete 100 kHz SMPS current-mode controllers with internal 65 V 1.25 A power switches. The MIC2172 features external frequency synchronization or frequency adjustment.
Although primarily intended for voltage step-up applications, the floating switch architecture of the
MIC2172 makes it practical for step-down, inverting, and Cuk configurations as well as isolated topologies.
Feature:
- 1.25 A, 65 V internal switch rating
- 3 V to 40 V input voltage range
- Current-mode operation
- Internal cycle-by-cycle current limit
- Thermal shutdown
- Low external parts count
- Operates in most switching topologies
- 7 mA quiescent current (operating)
- External frequency synchronization (MIC2172)
- External frequency trim (MIC2172)
- Fits most LT1172 sockets (see applications info)
Applications:
- Laptop/palmtop computers
- ToysHand-held instrumentsOff-line converter up to 50W (requires external power switch)
- Predriver for higher power capability
- Master/slave configurations (MIC2172)
