Frequently Asked Questions

What is the maximum output current the LTM4661EY#PBF can deliver?

The LTM4661EY#PBF supports a maximum continuous output current of 4A, making it capable of supplying multiple downstream loads in space-constrained designs with a wide adjustable output voltage from 2.5V to 15V.

Which input voltage range does the LTM4661EY#PBF support for boost conversion?

The device accepts an input voltage from 0.7V to 5.5V, with a nominal 3.3V rail, enabling boost conversion from single-cell Li-ion or alkaline batteries up to regulated outputs as high as 15V.

How does current-mode PWM control benefit the LTM4661EY#PBF in sensitive applications?

Current-mode pulse width modulation provides inherent cycle-by-cycle current limiting and improved transient response, delivering stable output voltage across load steps from 0A to 4A without requiring complex external compensation networks.

Is the LTM4661EY#PBF a suitable boost regulator for portable medical and IoT sensor designs?

Yes. Its compact 25-ball BGA footprint, wide 0.7V to 5.5V input range, and adjustable 2.5V to 15V output make it ideal for portable medical monitors, IoT sensor nodes, and wearables where board space is under 5 mm x 5 mm.
