Rated for -40°C to 125°C junction temperature, this part is comfortable in under-hood automotive, outdoor telecom cabinets, and factory-floor gear that sees heat and cold. No AEC-Q100 mark in the record, but the temp range alone tells you it is not a commercial-grade indoor-only part.
For volume BOMs or blanket orders, the RFQ process locks in allocation and lead time.
The switching frequency is adjustable from 100kHz to 2.2MHz via the Frequency Control pin. A resistor from that pin to ground sets the oscillator timing — the datasheet provides the resistor-value table for the target frequency.
