MAX16990ATCF/V+ is a DC-DC switching controller targeting various portable electronics applications such as tablet PCs, digital cameras, and industrial equipment. The device is part of a family of devices that includes the MAX16990ARMZ+ and MAX16990ATCF+ performance regulating step-down converters. The MAX16990ATCF/V+ provides high power density and accuracy. It also provides advanced features such as adjustable output current limit, adjustable soft-start, advanced housekeeping functions, and low-noise operation.

The MAX16990ATCF/V+ operates as a DC-DC step-down controller. It increases the voltage level of a control signal applied to the regulator’s input and provides it directly to the output of the regulator. It is designed to drive a power MOSFET, switching the power from the input to the output of the regulator. The main feature of the MAX16990ATCF/V+ is its ability to regulate the output voltage. This feature is important in ensuring that the voltage level applied to the output stays within the rated range, regardless of input voltage or output load changes.

The MAX16990ATCF/V+ operates at a high frequency of up to 2.0MHz, allowing for small external components and high efficiency levels. The switching frequency is adjustable using the internal clock-dithering feature, allowing for flexible design of regulators with a wide range of output voltages and current levels. In addition, the MAX16990ATCF/V+ has adjustable current limit, adjustable soft-start and other features to ensure its safe operation.

The MAX16990ATCF/V+ also features low-noise operation in order to reduce electromagnetic interference (EMI) generated by the regulator. This feature is achieved by implementing switching techniques that reduce the voltage fluctuations at the MOSFET’s gate and drain. This results in improved efficiency and reduced EMI. The device also includes a built-in temperature sensor, allowing the regulator to adjust the switching frequency and output current according to the temperature of the components in the system.

The MAX16990ATCF/V+ is an ideal solution for high-efficiency voltage regulating applications in consumer and industrial electronics. It is highly configurable, and its adjustable current-limit, soft-start, housekeeping functions, and low-noise operation make it a great choice for DC-DC step-down switching applications that require high power density, high accuracy and improved EMI performance.
