Furthermore, the device supports an active burst mode, allowing the system to reduce system power consumption and further extend battery life.

Working Principle of MAX15020ATP+T

The MAX15020ATP+T is a step-down DC-DC switching regulator that works in two distinct phases. The first phase is referred to as the “charging” phase, where the device generates power to charge the battery. During the “discharging” phase, the device converts power from the battery to output power for the application within certain voltage and current limits. The MAX15020ATP+T features an adjustable switching frequency up to 1.5MHz, which allows for greater flexibility when it comes to design choices. Additionally, the device features adjustable diode emulation mode, which allows for higher efficiency and less switching noise in light load applications. The MAX15020ATP+T supports non-synchronous rectifier operation for increased efficiency and can be used with a variety of external power components such as Schottky diodes, MOSFETs, and minimum-loss inductors. Additionally, the device offers on-board synchronous rectifier control and over-voltage protection. Finally, the MAX15020ATP+T includes an integrated Maximum Duty Cycle (MDC) control loop, which increases efficiency while ensuring proper regulation in the event of varying input or output voltages.

Conclusion

The MAX15020ATP+T is a competitively priced, versatile power solution that is ideal for use in DC-DC switching regulator applications in mobile, consumer, automotive, and industrial applications. With features such as adjustable switching frequency, diode emulation mode, non-synchronous rectifier operation, integrated over-voltage protection, active burst mode, and maximum duty cycle (MDC) control, the MAX15020ATP+T offers excellent performance under demanding environmental conditions.
