Product Overview
MAX25169 is a highly integrated TFT power supply and LED backlight driver IC for automotive TFT-LCD applications. This IC integrates one boost converter, one inverting buck-boost converter, two gate-driver supplies, and a boost/SEPIC controller that can power 1 to 6 strings of LEDs in the display backlight. The source-driver power supplies consist of a boost converter that can provide up to +18V in unipolar mode and an inverting buck-boost converter that can generate a voltage down to -10.5V. The positive source-driver supply-regulation voltage (VAVDD) is set using internal NV memory or through I2C. The negative source-driver supply voltage (VNAVDD) is always tightly regulated to -VAVDD. The source-driver supplies operate from an input voltage between 2.65V and 5.5V. Application includes automotive dashboards, automotive central information displays. automotive head-up displays, automotive navigation systems.
- Regulators with adjustable output voltage (tripler/inverting doubler)
- Flexible sequencing, undervoltage detection on all outputs
- Low-quiescent-current standby mode
- NGATE control for external NMOSFET series switch
- Programmable nMOSFET current limit
- Dimming ratio 16,667:1 at 200Hz
- Adaptive voltage optimization to reduce power dissipation in LED current sinks
- Open-string, shorted-LED, and short-to-GND diagnostics
- Phase-shift dimming of LED strings, spread spectrum on LED driver and TFT outputs
- 48 TQFN-EP package, temperature range from -40°C to +125°C
