Key Featrues
Wide Operating VIN Range (4.5V to 150V) - This feature allows the controller to handle a broad range of input voltages, making it suitable for diverse applications such as automotive, industrial, and telecommunication power systems. It enhances versatility and ensures reliable operation in high-voltage environments.
Very Low Dropout Operation (100% Duty Cycle) - The ability to operate at 100% duty cycle ensures minimal voltage dropout, enabling efficient power conversion even when the input voltage is close to the output voltage. This is particularly beneficial in applications requiring continuous power delivery.
Adjustable Input Overvoltage Lockout - This feature protects the system by allowing users to set a threshold for input voltage, preventing damage from overvoltage conditions. It enhances system reliability and safety in volatile power environments.
Selectable Burst Mode® Operation or Pulse-Skipping Mode - These modes optimize efficiency at light loads by reducing switching losses. Users can choose the mode that best suits their application, improving energy efficiency and extending battery life in portable devices.
Programmable PGOOD Undervoltage Monitor - This feature provides a signal when the output voltage falls below a user-defined threshold, enabling quick detection of faults or underperformance. It ensures system stability and aids in troubleshooting power management issues.
