MAXIM INTEGRATED / ANALOG DEVICES MAX16903SAUE33V High-Voltage Buck Converter
The MAX16903 is a compact, high-voltage synchronous buck converter operating at 2.1MHz, designed to deliver 1A output current. It features integrated high- and low-side switches, supporting input voltages from +3.5V to +28V with transient tolerance up to +42V. The device supports dropout operation at 97% duty cycle, enabling continuous power in automotive and industrial environments. Its flexible operation modes include forced fixed-frequency, skip mode for ultra-low quiescent current, and external synchronization. Available in 10-pin TDFN and 16-pin TSSOP packages, it offers enhanced efficiency, low EMI, and built-in overcurrent and thermal protection, making it suitable for space-constrained applications requiring reliable DC-DC step-down conversion.
