应用/用途

描述

The MAX16926 is a 4-channel power-management IC designed to accommodate the main rails used in modern automotive TFT displays. The MAX16926 and the MAX20069 TFT power supply and LED backlight driver combine to provide a two-chip solution to automotive display power supply requirements.

The MAX16926 integrates a high-voltage buck converter that transforms battery voltages into a 3.3V intermediate rail. In addition, a high-voltage, always-on, low-quiescent-current linear regulator supplies power at 3.3V.

The low-voltage section consists of a fully-integrated DC/DC converter and an LDO running off the intermediate rail. The low-voltage DC/DC converter provides 1.1V, while the LDO produces 1.8V. In addition, an integrated watchdog timer guards against runaway code.

A single START control pin initiates the start-up sequence, thereby simplifying device control. The MAX16926's external pMOSFET control block allows battery voltage to be switched to a downstream device, such as a backlight boost converter.

The MAX16926 is available in a TQFN package and operates in the -40°C to 105°C temperature range.
