MAX16501BGGB+T

Overview

The MAX16501BGGB+T is a high-voltage, synchronous step-down DC-DC converter belonging to the Himalaya family. It operates with an input voltage range of 4.5V to 60V and delivers up to 500mA of output current. The device integrates two N-channel power switches for efficient synchronous rectification and features a fixed switching frequency of 600kHz. It provides adjustable output voltages from 0.9V to 55.2V via an external resistor divider. Key protection features include cycle-by-cycle current limiting, thermal shutdown, and undervoltage lockout. The component is housed in a compact 10-pin TDFN package.

Feature Summary

• Integrates dual N-channel power switches for high-efficiency synchronous buck conversion
• Supports wide input voltage range suitable for industrial and automotive applications
• Includes comprehensive protection mechanisms such as thermal shutdown and current limit
• Features fixed-frequency operation to simplify external component selection

Applications

• Industrial automation control systems
• Automotive electronics and infotainment modules
• Distributed power supply architectures
• Battery-powered equipment requiring high-voltage tolerance

Procurement Notes

Verify the specific suffix 'BGGB+T' against the manufacturer's official datasheet to confirm pinout compatibility and tape-and-reel specifications. Ensure that the ordering information matches the exact temperature grade and packaging requirements defined in the latest product change notification (PCN). Cross-reference the component marking code with the manufacturer's guide to prevent counterfeit substitution.

Selection Notes

Select this component when designing systems requiring a single-stage conversion from high-voltage rails down to lower logic or analog levels. The integrated synchronous design reduces the need for external Schottky diodes, saving board space. Consider the 600kHz switching frequency for balancing efficiency and passive component size. Verify that the maximum output current requirement does not exceed the 500mA limit under all operating conditions.

Part Context

This part belongs to the Himalaya series of high-voltage DC-DC converters from Maxim Integrated, now part of Analog Devices. The series is designed for robust performance in electrically noisy environments. The MAX16501 variant specifically targets applications needing reliable regulation from inputs up to 60V. It complements other devices in the family like the MAX17501, which offers different switching frequencies.
