MAX16929CGUI/V+

The MAX16929CGUI/V+ from Analog Devices (Maxim Integrated) is a specialized power management integrated circuit designed for automotive TFT-LCD displays. This device integrates a buck converter, a boost converter, a regulator controller, and two gate voltage regulators, providing a comprehensive power solution for demanding automotive environments.

Key electrical features include an operating voltage range of 4V to 28V for the buck converter and 3V to 5.5V for the boost converter. The boost converter can deliver high power, up to 6W, with an output voltage of up to 18V. The integrated 1.8V or 3.3V regulator can supply 500mA with an external NPN transistor, and a positive-gate voltage regulator is capable of delivering 20mA at 28V. The device operates at high frequencies, with the buck converter at 2.1MHz and the boost converter at 2.2MHz, aiding in EMI performance.

Designed for automotive applications such as dashboards, central information displays, and navigation systems, the MAX16929CGUI/V+ incorporates features like flexible sequencing, power-good indication, and integrated thermal shutdown circuitry for protection. It also offers a low-current shutdown mode of 6µA for the buck converter and true shutdown for the boost converter, contributing to power efficiency.

The device is housed in a 28-pin TSSOP package with an exposed pad, suitable for surface mounting. It operates reliably within a temperature range of -40°C to +105°C.
