MAX16932ATIU/V+T

The MAX16932ATIU/V+T is a DC-DC switching controller designed to enable the design of efficient, cost optimised, synchronous step-down converters. The part is designed to enable multi-phase parallel operation of synchronous step-down switching controllers in a small footprint, making it ideal for space constrained applications.

The core of the MAX16932ATIU/V+T is a digital modulator circuit which regulates the output voltage in response to the input voltage and current. The output voltage range can be adjusted to optimise efficiency for the specific application and the device supports automated Multi-Phase Synchronous Rectification (MPR) for high efficiency load regulation. It is capable of operating from 2V to 40V input voltage and is ideal for applications requiring high voltage input with a large dynamic range.

The MAX16932ATIU/V+T supports programmable current limit, over-temperature protection, short-circuit protection and many other features to ensure robust operation of the converter in harsh environment. The device also offers provision for remote sensing of the output voltage, features to reduce EMI filter size and a programmable Soft-Start control which can be used to improve efficiency and reduce inrush current at the start-up.

The DC-DC switching controller has many application fields beyond simple step-down converters. It can be used in automotive, consumer and industrial applications such as LED backlighting, battery charging, motor control and many more. The MAX16932ATIU/V+T offers advanced features for efficient operation in these applications and has the flexibility to be configured for a variety of requirements.

In order to understand the function of MAX16932ATIU/V+T it is useful to discuss its working principle. It adopts a variable frequency digital pulse width modulation (DPWM) for accurate current and voltage control. This modulation scheme is capable of producing discrete switchable output voltages by adjusting the duty cycle of the input signal. The regulation loop of the module is implemented using a combination of voltage and current sensing signals (V SENSE, I SENSE) to maintain the output control at the set value. The module also implements on-chip intelligent control and protection features such as over-temperature, over-voltage, short-circuit and over-current protection.

The MAX16932ATIU/V+T DC-DC switching controller is ideal for applications where efficiency, cost and reliability are top priorities. It can enable highly efficient, cost optimised designs in automotive, consumer and industrial applications. The device offers features such as programmable current limit, over-temperature protection and short-circuit protection to ensure excellent operation reliability.
