MAXIM INTEGRATED / ANALOG DEVICES MAX5033DUSA Buck Converter

The MAX5033DUSA+ is a high-efficiency, high-voltage step-down (buck) DC-DC converter manufactured in an 8-pin NSOIC package. It operates across an input voltage range from 7.5V to 76V and features a quiescent current of only 270 microamps at no load. This PWM-based converter switches at a fixed frequency of 125kHz under heavy loads and automatically enters pulse skipping mode to maintain high efficiency and low quiescent current at light loads. It incorporates an internal low on-resistance, high-voltage DMOS transistor to optimize efficiency and reduce system costs. Additional features include undervoltage lockout, cycle-by-cycle current limiting, hiccup mode, output short circuit protection, and thermal shutdown. The device can deliver up to 500mA of output current, limited by maximum power dissipation of the package, and includes external shutdown functionality with a 10 microampere shutdown current. The converter offers up to 90% efficiency, operates in an automotive temperature range from -40°C to 125°C, and allows adjustable output voltages from 1.25V to 13.2V. It features an internal 0.4 ohm high-side DMOS FET and internal frequency compensation for simplified circuit design. The maximum duty cycle is 95%, making it suitable for various power management applications in industrial, automotive, and consumer electronics sectors.
