The MAX16963RATEA/V+ is an easy-to-use, high-efficiency, high-density, low-loss DC-DC switching regulator. It is a monolithic power converter and integrated power security components, including low-dropout regulators, gate drivers, boost converters and synchronous rectifier drivers. This device enables easy integration of voltage and current regulation, safety and power management, while keeping the physical size of the system as small as possible.

The MAX16963RATEA/V+ is suitable for multiple application fields and environments. Its versatile capabilities are well-suited for applications in automotive, computing, power management and communications. The device is particularly adapted for switching power supplies in small- to mid-sized servers and small handheld devices. It can also be used for mobile device applications like automotive, cellphones, PDAs, digital cameras and laptops.

The MAX16963RATEA/V+ working principle is based on a PFM (pulse-width modulation) control scheme. This principle is used to allow efficient current mode power conversion in a wide range of output power levels and environmental conditions. When enabled, the device monitors the output voltage and reacts to changes in the output voltage by dynamically adjusting the duty cycle of the converter. This prevents the output voltage from exceeding the intended level and eliminates the need for external components to adjust the voltage. Additionally, the device allows parallel and series operation of multiple switches to increase the power handling capability of the system without having to increase the switching frequency.

The MAX16963RATEA/V+ provides built-in features such as over-voltage protection, under-voltage protection and over-temperature monitoring. It also includes a proprietary added-noise filter to reduce switching noise and harmonics in the output voltage. Furthermore, the device provides adjustable soft-start and hiccup current limit functions to control current spikes and minimize start-up time. Additionally, it comes with a user selectable auto-restart function which automatically re-starts the switching regulator if it reaches its over-temperature or over-current limit.

In conclusion, the MAX16963RATEA/V+ is an easy-to-use, high-efficiency, high-density, low-loss DC-DC switching regulator. Its versatile features make it suitable for a wide range of applications in automotive, computing, power management and communications. Its PFM control scheme ensures efficient current mode power conversion while providing built-in features like over-voltage and under-voltage protection, over-temperature monitoring and a proprietary added-noise filter for reduced switching noise. The device also includes adjustable soft-start and hiccup current limit functions as well as a user selectable auto-restart function.
