Frequently Asked Questions

Can MAX1556AETB+ operate directly from a single-cell Li-ion battery, and what output voltages does it support?

Yes. MAX1556AETB+ accepts input from 2.6 V to 5.5 V, covering the full single-cell Li-ion discharge range of about 3.0 V to 4.2 V, and provides fixed 2.5 V or 3.3 V outputs, as well as an adjustable mode spanning 0.75 V to 5.5 V for flexible rail generation.

How does the 3x3 mm LFCSP package of MAX1556AETB+ benefit space-constrained wearable and IoT PCB designs?

The 10-pin LFCSP measures only 3x3x0.75 mm, providing one of the smallest footprints available for a current-mode PWM step-down converter, which is critical in wearable and IoT modules where total PCB area is often below 20 square millimeters for the entire power section.

What sourcing outlook does MAX1556AETB+ carry for a product program expected to run 5 to 10 years?

MAX1556AETB+ carries a YTEOL of 10 years, indicating continued active production through at least the mid-2030s under normal lifecycle policy. This gives procurement teams confidence to commit to multi-year supply agreements and qualify the part for long-lifecycle consumer and industrial product platforms.
