Frequently Asked Questions
What is the switching frequency of the LT3489EMS8E#PBF and why does it matter for inductor selection?
The LT3489EMS8E#PBF switches at 2MHz, which allows designers to use inductors as small as 1 µH to 4.7 µH while maintaining good efficiency. Higher switching frequency reduces inductor size and output ripple, making the regulator ideal for compact PCB layouts where board space is at a premium.
What input voltage range does the LT3489EMS8E#PBF support, and can it run from a single-cell lithium battery?
The LT3489EMS8E#PBF accepts input voltages from 2.6V to 16V, comfortably covering a single-cell Li-Ion battery's discharge range of approximately 2.7V to 4.2V. This makes it directly usable in battery-operated devices without any pre-regulation stage, simplifying the overall power tree design significantly.
How much output current can the LT3489EMS8E#PBF deliver in a step-up boost configuration?
In a boost step-up configuration the LT3489EMS8E#PBF can deliver up to 2.5A of switch current, enabling output currents typically in the range of 500mA to 1A at 5V output from a 3V input. The exact deliverable output current depends on input-to-output voltage ratio and inductor DCR losses.
What control topology does the LT3489EMS8E#PBF use and what are its stability advantages?
The LT3489EMS8E#PBF uses current-mode pulse width modulation (PWM) control. Current-mode control provides inherent cycle-by-cycle peak current limiting, faster transient response compared to voltage-mode PWM, and simpler compensation networks. These advantages make it easier to stabilize across a wide range of output capacitor values.
Is the LT3489EMS8E#PBF available in a lead-free package and what is its body size?
Yes, the #PBF suffix confirms the LT3489EMS8E#PBF is fully lead-free and RoHS-compliant. It is housed in an MSOP-8 (MS8E) package with a body measuring approximately 3mm x 3mm, offering 8 pins in a small outline form factor suitable for high-density PCB designs.
