MAX20430ATIBB/VY+

Power Management - Specialized Overview

The MAX20430ATIBB/VY+ is a four-output mini PMIC designed for safety applications, featuring boost and buck DC-DC switching regulators. It operates with an input voltage range of 3.5V to 40V and provides positive outputs configurable at 0.8V, 3.3V, or 5V, with a maximum output voltage of 3.9875V. The device delivers output currents of 500mA, 2.5A, 3A, and 3A across its four channels. Operating at a fixed switching frequency of 2.1MHz, it utilizes synchronous rectification and is housed in a 28-SWTQFN (5x5) package with exposed pad.

Power Management - Specialized Procurement Notes

Verify the specific suffix 'BB' against the official Analog Devices datasheet to confirm exact pinout and functional configuration, as suffixes often denote specific package variants or internal revisions. Ensure the component meets RoHS3 and REACH compliance standards required for your assembly process. Cross-reference the 28-SWTQFN footprint dimensions with your PCB design guidelines to ensure accurate placement and thermal performance during manufacturing.

Power Management - Specialized Selection Notes

Select this component when a high-voltage input range up to 40V is required alongside multiple regulated outputs in a small form factor. It is suitable for designs needing integrated boost and buck capabilities within a single safety-certified package. Consider the 2.1MHz switching frequency for EMI management and the specific current ratings of 500mA to 3A per channel to match load requirements without exceeding thermal limits in the 28-SWTQFN enclosure.
