The MAX16962SATEA/V+ is a high efficiency, wide input voltage dual output DC-DC step down (buck) converter embedded with a low-side FET for automotive applications.

The device allows up to 4 A output current with up to 20 V input voltage range, operating at a fixed switching frequency of 2 MHz. It is designed with integrated MOSFETs to reduce parts count and size, as well as optimize efficiency at light load. It also features programmable soft-start control, output voltage tracking, voltage spread, short-circuit protection, thermal shutdown, and undervoltage lockout.

It is designed to work with a low-quiescent current, making it ideal for ultra-low-power applications, such as putting cellular modems in standby mode. The device operates with supply voltages up to 40 V, providing necessary flexibility and an extended temperature range from -40 to +105 °C.

The MAX16962SATEA/V+ uses synchronous rectification for maximum efficiency and fast, low-impedance output voltage switching. It also features a low-side FET for active in-rush current limiting, and a programmable soft start for load sharing applications. The device is available in a 16-pin TQFN (4 mm x 5 mm).

The MAX16962SATEA/V+ is a versatile DC-DC switching regulator, suitable for low-power automotive applications such as radio and audio amplification, portable navigation systems, automotive ECUs, and GPS tracking and communication systems. Its wide input voltage range and high maximum current rating make it suitable for systems with power demands up to 15 W, including those powered with 12 or 24 V.

At the heart of the MAX16962SATEA/V+, is the integrated oscillator and current regulators, which work together in order to ensure reliable and consistent performance across a wide range of operating conditions. The oscillator is set to 2 MHz and the current regulator is adjustable between 0.3 A to 4 A, with the ability to switch from 1 A to 3 A in less than 25 us. This fast response time makes the MAX16962SATEA/V+ ideal for systems with dynamic load changes.

The MAX16962SATEA/V+ also features protection for overvoltage, undervoltage, over-current, thermal overload and short-circuit conditions. It has a shield pin, which reduces EMI radiation, and a built-in soft start, which limits in-rush currents. Additionally, the device includes a voltage spread function, which reduces noise and inrush current.

In conclusion, the MAX16962SATEA/V+ is a robust and reliable DC-DC switching regulator, suitable for low-power automotive applications. Its wide range of features, including a wide input voltage range, fast response time, and integrated protection circuits, make it an ideal choice for automotive systems that require high efficiency, reliability and flexibility.
