Application Field of MAX5021

The MAX5021 is suitable for applications such as multi-output buck Point of Sale Power Supplies (PSPs) and point-of-load DC-DC converters. The MAX5021 is an ideal choice for applications requiring fast transient response, low operating and standby current, high output accuracy, and wide input voltage range. It is ideal for automotive, industrial, and medical applications.

Working Principle of MAX5021

The MAX5021 is a PWM (Pulse Width Modulation) controller with an internal oscillator, providing a precise switching frequency over temperature. The controller has an integrated high-side MOSFET gate driver and can operate in either a fixed frequency or Burst Mode operation. In fixed frequency mode, the switching frequency is set with an external resistor, and the following features can be programmed using external resistors: peak current limit, soft-start and output voltage. In Burst Mode operation, the duty cycle is modulated as a function of the input/output voltage ratio, and a selectable frequency skip mode increases efficiency by reducing switching frequency when the load is light. These features, along with the high efficiency of the MOSFETs and integrated Gate drivers, make the MAX5021 an ideal choice for energy-sensitive applications.

The MAX5021 has numerous protection features, including overvoltage protection (OVP) and undervoltage protection (UVP). Dynamic overvoltage protection (DOP) is also included in the MAX5021, ensuring that the output voltage never exceeds a set value, even under extreme conditions. The MAX5021 also features a power-saving low dropout (LDO) pin voltage, selectable oscillator frequency, and soft-start circuitry, making it simpler to design and configure.

In addition to all the features described above, the MAX5021 includes a built-in temperature-compensated supply voltage monitor which, when configured correctly, ensures that the output voltage remains in regulation, even if the input voltage is within tolerance and the load is heavy.

In summary, the MAX5021 is a high-performance switching regulator controller suitable for use in a wide range of applications, including point-of-load DC-DC converters and multi-output buck PSPs (Point of Sale Power Supplies). The MAX5021 provides fast transient response, low operating and standby current, high output accuracy, and wide input voltage range, making it ideal for automotive, industrial, and medical applications.
