Frequently Asked Questions (FAQ)
Q: Are the R1211D100A-TR-FE and R1211D002B-TR-FE pin-compatible?
A: Yes. Both devices use the 6-SON (2.6x1.6) package with identical pinout and flat lead configuration, enabling direct PCB footprint compatibility.
Q: Can I substitute R1211D002B-TR-FE for R1211D100A-TR-FE in an existing design?
A: Yes. All electrical parameters, including PWM output type, boost topology, supply voltage range (2.5V ~ 6V), switching frequency (700kHz), and duty cycle (90% maximum) are identical. No circuit modifications are required.
Q: What is the difference between these two part numbers?
A: The part numbers reflect different internal configurations or mask revisions within the R1211 base product family. Electrical and mechanical specifications are equivalent. The primary difference is inventory availability.
Q: Are both parts RoHS compliant?
A: Yes. Both R1211D100A-TR-FE and R1211D002B-TR-FE are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating.
Q: What is the operating temperature range for these controllers?
A: Both parts operate across -40°C to 85°C, suitable for industrial and commercial temperature environments.
Q: Can these parts be used in applications requiring synchronous rectification?
A: No. Both the R1211D100A-TR-FE and R1211D002B-TR-FE do not include integrated synchronous rectifier functionality. External rectification components are required in boost converter designs.
Q: Is clock synchronization available on these devices?
A: No. Neither part supports clock synchronization features. Switching frequency is fixed at 700kHz.
