MAX786CAI+

Overview

The MAX786CAI+ is a dual-output power-supply controller designed for notebook computers and battery-powered equipment. It integrates two high-performance step-down pulse-width modulators (PWMs) for generating +3.3V and +5V rails. The device supports an input voltage range of 5.5V to 30V with fixed output options including 3.3V, 3.45V, and 3.6V. Key electrical specifications include a quiescent current of 420µA, standby current of 70µA, and shutdown current of 25µA. It achieves up to 95% efficiency and is housed in a 28-pin SSOP package.

Feature Summary

• Integrates dual PWM buck controllers for efficient voltage regulation
• Includes precision low-battery detection comparators
• Features low quiescent and standby currents for extended battery life
• Supports multiple fixed output voltages for processor compatibility

Applications

• Notebook computers
• Portable data terminals
• Communicating computers
• Pen-entry systems

Procurement Notes

Verify the specific suffix CAI against the official datasheet to confirm temperature grade and packaging type. Confirm RoHS compliance status as indicated by the plus sign. Check for end-of-life notifications or discontinuance alerts from Analog Devices prior to finalizing procurement plans.

Selection Notes

Select this component when designing power architectures for portable devices requiring dual regulated outputs from a wide input range. Ensure the thermal performance of the SSOP-28 package meets the system's dissipation requirements under maximum load conditions.
