Working Principle

The MAX775ESA+ is a highly efficient, integrated DC-DC controller specifically designed to facilitate the power applications of portable electronics requiring high efficiency, small size, and fast transient response times. The device features a pulse-width-modulated (PWM) controlled integrated buck converter with maximum output current of 1 amp and the output voltage is adjustable with external resistors. The quiescent current of the controller is 2.2mA, allowing for low power consumption.

The controller has continuously adjustable output voltage levels between 1.8V and 5.5V, with output voltage accuracy of +/-1%. The maximum operating frequency of the controller is 1.2MHz, which allows for fast transient response. The device is designed to minimize EDM, minimize noise and EMI, and provide automatic bias compensation for optimum OVP threshold accuracy.

The MAX775ESA+ has a wide input operating range between 2.7V and 5.5V and is designed to switch up to 1.2MHz with the internal oscillator. The device also features cycle-by-cycle over-current limit and short-circuit protections. The device also features a switch current limit of 1A and an external shutdown pin, allowing the device to be shut down while saving power. Finally, the device also has an integrated low-dropout linear regulator with 200mA current limit, providing a stable output voltage even when the input voltage drops as low as 2.7V.
