Introduction
The MAX16990ATCC/V+ is a DC-DC switching controller specifically designed for step-down power applications. It provides high efficiency with wide output voltage range, low regulating error and low minimum on-time. It supports a wide input voltage range from 2.4V to 35V and offers a high switching frequency range from 65kHz to 1MHz. This makes it suitable for distributed power systems and communication/Instrumentation power applications. It also features integrated adaptive voltage positioning (AVP) control, which allows for dynamic voltage control.Features
The MAX16990ATCC/V+ features a wide input voltage range from 2.4V to 35V, high switching frequency from 65kHz to 1MHz, and up to 96% efficiency. It also features integrated adaptive voltage positioning (AVP) control, which allows for dynamic voltage control. It includes an internal programmable softstart function and good transient response. The device also offers adjustable frequency range (FOSC) and programmable power-saving modes. The MAX16990ATCC/V+ also includes a programmable spread spectrum clock (SSC), which reduces the EMI noise.Applications
The MAX16990ATCC/V+ is ideal for distributed power systems and communication/Instrumentation power applications. It is suitable for desktop PCs, servers, telecom systems, datacenters, and high-end industrial/automotive applications. It can also be used for low-voltage, high-current DC/DC applications such as isolated DC/DCs, isolated bus converters, and AC/DC, DC/DC and DC/AC converters.Working Principle
The MAX16990ATCC/V+ is a Pulse Width Modulated (PWM) voltage regulator designed to control the output voltage of a load by varying the width of the switching signal generated. The device utilizes a voltage feedback loop, which is automatically adjusted based on the current and voltage sense measurements. The device includes a 400V MOSFET integrated power switch to provide an efficient, low-power solution with low total harmonic distortion (THD). The device uses a programmable softstart function to ensure that the output voltage is controlled within the specified range during start-up. The device also contains a high-frequency precision voltage reference, integrated voltage sensing and an LF compensation network to ensure a fast response to current and load fluctuations. Additionally, it can be programmed to reduce the EMI noise by using a programmable spread spectrum clock (SSC) feature.Conclusion
The MAX16990ATCC/V+ is a DC-DC switching controller for step-down power applications. It provides wide output voltage range, low regulating error, high efficiency and low minimum on-time. It features a wide input voltage range from 2.4V to 35V, adjustable frequency range (FOSC) and programmable power-saving modes. It also includes an internal programmable softstart function, good transient response and a programmable spread spectrum clock (SSC) to reduce the EMI noise. This makes it suitable for distributed power systems and communication/Instrumentation power applications.The specific data is subject to PDF, and the above content is for reference
