Maxim’s MAX761ESA is a DC-DC switching regulator product specifically designed to provide low dropout control to drive step-down and step-up regulators. It combines a switching regulator, linear regulator and reset circuit into a single integrated package for superior performance and ease of use. With a wide input voltage range, it can efficiently deliver up to 4A or 8A of continuous current. This makes it suitable for automotive, industrial and consumer applications that require high-efficiency, low-power dissipation and fast transient response.

The MAX761ESA has an internal output voltage regulator, so that the output voltage is set by an external voltage divider. The device features a built-in reference generator and a high-precision comparator to provide stable output voltage control. The reference generator\'s output is digitally controlled, so the output voltage can be programmed by setting the divider resistors. An internal oscillator maintains the switching frequency of the power converter, and a current-limiting circuit ensures short-circuit protection.

The MAX761ESA also features a dynamic power limiting circuit that protects against overloads, and an integrated low dropout linear regulator that keeps the device’s output voltage within 1% of its programmed value. The device also incorporates a soft-start feature for superior transient response, and an active-high enable pin that allows for easy programming of the output voltage. Additionally, the device has an advanced control algorithm that maintains high efficiency throughout the entire operating range.

The device’s integrated linear regulator allows for precise regulation of the output voltage, even in the face of input voltage variations, making it ideal for automotive, industrial and consumer applications. The MAX761ESA’s wide input voltage range (4.7V to 20V) allows it to operate from almost any available power supply, and its built-in protection circuitry ensures safe operation in the presence of short-circuit and over-current conditions. Additionally, the device’s wide operating temperature range (-20°C to +85°C) ensures reliable operation in even the harshest of environments.

The MAX761ESA is ideal for a broad range of applications that require precise power regulation. Its low external component count, high-performance, wide input voltage range and integrated protection circuitry make it an ideal choice for a variety of switching regulator applications. Maxim’s MAX761ESA is an ideal solution for any application that requires a low-dropout, high-efficiency, wide-load range and fast transient control.
