Frequently Asked Questions
What is the maximum output current of LT1268CQ#PBF and which load types can it drive reliably?
The LT1268CQ#PBF supports up to 7.5 A peak switch current, enabling continuous output currents of 5 A to 6 A depending on duty cycle and thermal conditions. This is sufficient for powering FPGAs, DSPs, multi-core processors, and high-current motor driver pre-stages in industrial boards.
How does LT1268CQ#PBF perform across the 3 V to 30 V input range in practical power supply designs?
Operating from 3 V to 30 V input, it covers single-cell Li-ion batteries, 5 V USB rails, 12 V automotive supplies, and 24 V industrial bus inputs in a single design. Its 150 kHz switching frequency keeps external inductors small across this wide input range without sacrificing efficiency.
When would a designer choose LT1268CQ#PBF over a lower-current alternative like LT1765?
When load currents exceed 3 A continuously, the LT1268CQ#PBF is the better choice with its 7.5 A switch rating and robust 5-lead power package offering lower thermal resistance. For loads below 2 A, smaller alternatives save board space and cost while delivering equivalent voltage regulation accuracy.
