It has a maximum output current of 1.2A, and it can also provide high efficiency up to 98%. It has a standard sleep mode feature to reduce power consumption when the system is idle, as well as maximum cycle frequency of 1.2MHz and a programmable power-on reset time of 50 to 300µs.

Applications

MAX641AESA+T voltage converters are ideal for applications such as high power industrial, consumer, and automotive systems. Some of the potential applications include power supplies, chargers, distributed power systems, server and storage solutions, battery-powered systems, and automotive modules.

Working Principle

The MAX641AESA+T features an integrated low resistance P-channel MOSFET power switch, which is designed to switch on and off at a high frequency, called the switching frequency. The switching frequency determines the efficiency of the voltage converter and is usually in the range of 100kHz to 1 MHz. When the MAX641AESA+T is connected to an external power supply, such a battery or a power adapter, it will regulate the output voltage. The specific output voltage range that is available to the user is adjustable and can be programmed using pins located on the device. In addition, the MAX641AESA+T also features protection against overcurrent, over temperature, and undervoltage.
