Working Principle

The MAX5035BUSA+ implements a two-phase synchronous buck regulator. The voltage is regulated by switching the power MOSFETs between the output and the input in two separate phases. The device is balanced between the two phases and provides a low output ripple. In addition, it can provide programmable overcurrent protection and thermal shutdown for system protection. Its integrated compensation and output drive blocks enable designers to achieve a very fast transient response time and high efficiency.

The MAX5035BUSA+ has adjustable switching frequency, allowing for optimal efficiency. The device also features a wide range of output voltage accuracy, from 0.5% to 1.5%, and can be used for supplies with high accuracy needs, thus making it suitable for telecommunication applications as well. Additionally, the device also supports hysteretic current-mode control for improved transient load and line response. User-adjustable soft start and programmable slope compensation helps reduce output voltage overshoot and pop during start-up.

The MAX5035BUSA+ includes two dual independent current-mode control channels and can be configured in parallel or in series operation modes. The two channels can be used to connect two loads simultaneously while keeping the output voltage constant. In addition, the device provides low noise operation, a POWER-GOOD output and can be programmed to run in a wide range of operating frequencies.

The MAX5035BUSA+ also has auto-one-phase current balancing that allows it to automatically adjust the operating frequency for optimal performance. In addition, the device has a wide operating temperature range from -40°C to +125°C, making it suitable for use in harsh environments. Its low-RDS(on) MOSFETs also help to save power in applications requiring heavy load currents.

The device also features wide and adjustable loop compensation with infinite bandwidth and fast transient response. This helps to ensure accurate output regulation in applications where quick transient load changes are common. Furthermore, the device supports a wide range of output voltages, enabling it to be used in applications with different power requirements.

Overall, the MAX5035BUSA+ is a dual step-down PMIC switching regulator suitable for a wide variety of applications. It provides wide input voltage and output current ranges, fast transient response times and high efficiency. In addition, it offers low quiescent power and wide operating temperature range making it suitable for automotive, datacom and industrial applications.
