Product Details

The MAX16923 is a 4-channel power-management IC designed to accommodate the main rails used in modern automotive TFT displays. The MAX16923 and the MAX20069 TFT power supply and LED backlight driver combine to provide a two-chip solution to all automotive display power-supply requirements.

The MAX16923 integrates a high-voltage buck converter that transforms battery voltages into a 5V or 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. Section output power is available in several low-voltage combinations (see the Ordering Information table). 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 MAX16923's external pMOSFET control block allows battery voltage to be switched to a downstream device, such as a backlight boost converter.

The MAX16923 is available in a TQFN package and operates in the -40°C to 105°C temperature range.
