Frequently Asked Questions

What input voltage range does the MAX1632EAI+ support, and is it compatible with both battery and adapter power inputs?

The MAX1632EAI+ accepts an input voltage from 4.2 V minimum to 30 V maximum, with a 15 V nominal operating point. This covers both Li-ion battery packs (around 7 V to 12 V) and typical AC adapter rails in notebook designs.

How does the current-mode control architecture of MAX1632EAI+ benefit multi-output notebook power designs?

Current-mode PWM control in the MAX1632EAI+ provides cycle-by-cycle overcurrent limiting and improved transient response compared to voltage-mode controllers. For notebook designs with 2 regulated outputs, this means faster load-step recovery and better protection against short-circuit conditions.

Which package does the MAX1632EAI+ use, and what does that mean for PCB layout in space-constrained notebooks?

The MAX1632EAI+ is supplied in a 28-pin SSOP with a 5.3 mm body width, enabling a compact PCB footprint suitable for space-constrained notebook motherboards and small-form-factor embedded computing modules compared to an equivalent DIP-28 solution.

Is MAX1632EAI+ still in active production, and what should buyers consider when planning inventory?

The MAX1632EAI+ was introduced in 1996 and has a limited remaining YTEOL horizon of approximately 3 years, suggesting it is approaching end-of-life. Buyers should verify current lifecycle status and consider building safety stock or evaluating newer multi-output PWM controllers as long-term alternates.
