TPS51727

illustrate

The TPS51727 is a complete, integrated lower gate driver controller. The PCNT pin enables dual or single-phase mode to operate with optimized efficiency load requirements. The advanced D-+ architecture provides fast transient response with minimal output capacitance. The DAC supports dynamic optimization of the operating state of the output voltage system on VID to meet idle power consumption requirements. Automatically skip single, dual-stage operation TPS51727 function to optimize light load efficiency. System management functions, including adjustable temperature sensors, output power sleep status monitoring and control. Adjustable VOUT's voltage slew rate and positioning control are provided.
