MAX16935RAUE/V+T

MAX16935RAUE/V+T is a high efficiency, two-phase interleaved, monolithic synchronous DC/DC Step Down Switching Regulator with an integrated 192mΩ Power MOSFET. A Digital Pulse Width Modulation (PWM) control system makes it possible to generate output voltages with a very low ripple and quiescent current, enabling converters with very high efficiency. This product is designed for applications with low output current and high-accuracy output voltage stability.

Application Field

The MAX16935RAUE/V+T is suitable for a wide range of consumer and industrial applications. It operates from a wide input voltage range extending from 2.7V to 28V and delivers an output voltage adjustable from 0.8V to 4.5V. This makes it well suited for applications such as hand-held consumer electronic devices, set-top boxes and TV accessories, automotive electronic systems, and industrial power supplies.

Working Principle

The MAX16935RAUE/V+T is capable of achieving very high efficiency. The PWM control system generates a regulated output voltage with a minimal amount of quiescent current, enabling high efficiency even at light loads. The control system operates over a wide range of temperature and supplies and can drive a step-down synchronous converter from 2.7V to 28V.

The MAX16935RAUE/V+T operates by synchronizing the frequency of the output voltage waveform to match the input voltage waveform cycle by cycle. This allows the output voltage waveform to be guaranteed and makes it possible to achieve a high degree of accuracy and clean output voltage waveform.

The synchronous DC-DC converter is designed to have variable frequency operation to balance the synchronous rectification\'s conduction and turn-off losses during transition. To ensure stable operation and to keep the output voltage regulation accurate, the control loop monitors the output voltage with a built-in control loop circuit.

The MAX16935RAUE/V+T also features a high level of fault protection. It includes under-voltage and over-voltage lockouts, as well as over-current protection and thermal shutdown.

Conclusion

The MAX16935RAUE/V+T DC-DC switching regulator can offer high efficiency, high accuracy, and high reliability for applications requiring low power and high voltage stability. It operates from a wide input voltage range extending from 2.7V to 28V and delivers an output voltage adjustable from 0.8V to 4.5V. In addition, it offers an integrated 192mΩ Power MOSFET for higher efficiency and over-current protection for improved reliability.
