Frequently Asked Questions
What input voltage range does LTC3119HFE#PBF support, and how does it handle buck-boost transitions?
The LTC3119HFE#PBF accepts an input voltage from 2.5 V to 18 V and automatically transitions between buck and boost modes to maintain a stable output. This seamless operation is critical for battery-powered systems where the battery voltage crosses the regulated output voltage, such as a 3.3 V rail from a Li-ion cell ranging 2.7 V to 4.2 V.
For a 5 A load application, how does LTC3119HFE#PBF compare to a standard buck converter solution?
Unlike a standard buck converter limited to step-down operation, LTC3119HFE#PBF delivers up to 5 A output across its full 2.5 V to 18 V input range in both buck and boost modes. This eliminates the need for separate step-up and step-down converters, reducing BOM count and board space in designs with a wide-ranging supply rail.
What output voltage can be set with LTC3119HFE#PBF, and what sets the minimum output?
The output voltage of LTC3119HFE#PBF is adjustable from 0.8 V to 18 V using an external resistor divider. The 0.8 V reference sets the minimum programmable output, making the device compatible with modern low-voltage digital loads such as DSPs and FPGAs operating at sub-1 V core voltages.
