Key Specifications
Description
The MAX16927 is a highly integrated power supply for automotive TFT-LCD applications. The device integrates one buck converter, one boost converter, one Cuk converter, two gate-voltage controllers, and two VCOM buffers, one of which supports negative output voltages.
Key Features
- Spread spectrum is always enabled for the buck converter, but enabled through an external input (SSEN) for the boost and Cuk converters
- Additional EMI enhancement is achieved by running the boost and Cuk converters 180° out-of-phase
- The device includes a control output for an nMOS switch to enable flexible sequencing of the negative VSL output
- A drive output is also included for a series pMOS switch for the boost converter allowing True Shutdown™
- The device is available in a 48-lead TQFN package with an exposed pad, and operates over the -40°C to +105°C temperature range
