Frequently Asked Questions
What input voltage range does the LTC3769EUF#PBF support, and how does that affect design flexibility?
The LTC3769EUF#PBF accepts an input voltage from 4.5 V to 60 V, giving designers the flexibility to source power from a wide variety of rails including 12 V automotive batteries, 24 V industrial buses, or 48 V telecom supplies without redesigning the controller stage.
At what switching frequency does the LTC3769EUF#PBF operate, and what impact does that have on magnetics sizing?
The controller operates at up to 900 kHz switching frequency, which allows the use of smaller inductors and capacitors compared to lower-frequency designs. For a 12 V input boosting to 24 V at 5 A, a 4.7 µH inductor may suffice, saving significant board area and BOM cost.
How does the LTC3769EUF#PBF compare to a fixed-frequency 400 kHz boost controller for automotive applications?
Compared to a 400 kHz fixed-frequency boost controller, the LTC3769EUF#PBF's 900 kHz capability reduces inductor size by roughly 50% and improves transient response, which is critical in automotive systems where load steps can exceed 10 A within microseconds. Its 60 V input rating also provides margin for load-dump transients up to 58 V.
