描述
The MAX16929 is a highly integrated power supply for automotive TFT-LCD applications. The device integrates one buck converter, one boost converter, one 1.8V/3.3V regulator controller, and two gate voltage regulators. The device comes in several versions to satisfy common automotive power-supply requirements (see the Ordering Information/Selector Guide table in the full data sheet).
Designed to operate from a single 4V to 28V supply or 5.5V to 28V supply, the device is ideal for automotive TFT-LCD applications. Both the buck and boost converters use spread-spectrum modulation to reduce peak interference and to optimize EMI performance.
The sequencing input (SEQ) allows flexible sequencing of the positive-gate and negative-gate voltage regulators. The power-good indicator (PGOOD) indicates a failure on any of the converters or regulator outputs. Integrated thermal shutdown circuitry protects the device from overheating.
The MAX16929 is available in a 28-pin TSSOP package with exposed pad, and operates over the -40°C to +105°C temperature range.
