DC-DC Switching Regulator

A DC-DC switching regulator is an electronic circuit that regulates voltage and current levels to control the output of a power supply. It is used to convert one DC voltage to another, or to convert a DC voltage to an AC voltage. Switching regulators work by switching on and off an inductor, or series of inductors, to change the voltage and current of the incoming DC signal in order to produce the desired output voltage and current. The switching frequency of the device is typically very high, usually in the range of kHz or tens of kHz.

MAX17542GATB+T Application Fields

The MAX17542GATB+T is a suitable device for a wide range of power management applications, such as powering process controllers, powering data logger systems, providing backup power to telecommunications systems, providing intermediate voltage to LED lighting systems, and more. It is suitable for use in automotive applications where space is limited and efficiency is paramount. The device has a wide input voltage range of 3V-3.6V, allowing for the use of low battery voltage sources, such as lead acid or nickel-cadmium rechargeable batteries. It is also designed with a quiescent current of 0.15mA and a wide output voltage range of 0.9V-3.2V, making it ideal for use in applications with severe power-saving requirements.

MAX17542GATB+T Working Principle

The MAX17542GATB+T is based on a switching regulator topology called a Synchronous Buck Regulator. It works by using two transistors (MOSFETs) to switch current through an inductor, causing the output voltage to dual with the input voltage. The two MOSFETs switch at different rates, allowing for a high level of efficiency, as energy is not wasted on voltage drops. When the output voltage reaches the desired level, the inductor is turned off, allowing for precise output voltage control. The device has an internal 1MHz oscillator, which can be overridden for higher frequency operation.

Conclusion

The MAX17542GATB+T is a highly efficient, low quiescent current DC-DC switching regulator with an integrated 1MHz oscillator and a wide input and output voltage range. It is suitable for a wide range of power management applications, both in automotive and non-automotive applications. With its excellent performance and its low power consumption, the MAX17542GATB+T is an ideal choice for power management systems in portable or datalogger applications.
