MAX14576EVB+T

MAX14576EVB+T is a member of the MAX14576 family, which is a power management integrated circuit (PMIC). It is designed to operate in industrial and automotive applications. This device provides a regulated supply voltage for systems that need to operate over extended temperature ranges. The device also has an optimized efficiency in light-load applications and can sustain a wide input voltage range up to 60 V. The device has an adjustable output voltage range of 0 to 28 V via a pulse-width modulation (PWM) or an adjustable voltage slope (AVS) mechanism. Additionally, it can also support an adjustable frequency range of 300 kHz to 2 MHz.

This device is well-suited for a variety of power management applications, such as automotive, industrial, and communication systems. The device features an adjustable slot protect function that prevents the MOSFET power switches from being damaged due to overload or underload. It also features a fault-protection circuit, which shuts down the output voltage in case of an overcurrent or overvoltage condition. The device’s clear enable control signal helps to improve the system’s reliability and prevent unwanted operation.

In terms of its working principle, this device uses a buck-boost topology to boost or reduce the voltage as required. The buck-boost structure differs from the conventional buck topology in that it can both boost and lower the voltage level from the input to the output. For this, the device utilizes internal power MOSFETs to step down or step up the voltage levels. It features an internal PWM that allows for continuous operation.

The MAX14576EVB+T device also features a low quiescent current, making it ideal for applications in which standby modes frequently occur. Its thermal shutdown feature secures the system from overheating by automatically shutoff in the case of over-temperature. The device also supports fixed-frequency or synchronized operation, which helps reduce EMI/RFI issues.

In summary, MAX14576EVB+T is a versatile power management integrated circuit (PMIC) designed for a wide range of industrial and automotive applications. Its adjustable output voltage range enables it to boost or lower the level of view when required. Its fault-protection and slot protect functions improve the system’s reliability and prevent unwanted operation. Its low quiescent current and thermal shutdown feature ensure maximum system protection and optimal performance.
