Description
VBATT (Pin 1)
Supplies all the power necessary to operate the chip.The IC starts to operate when the voltage on this pin exceeds 4.7V and stops operating when the voltage on this pin drops below approximately 4.5V.Also provides battery voltage to the oscillator for feed-forward rejection to input voltage variations.controllers.The PGOOD, overvoltage protection (OVP) and undervoltage
Features
- Provides Five Regulated Voltages - +5V ALWAYS - +3.3V ALWAYS - +5V Main - +3.3V Main - +12V.
- High Efficiency Over Wide Line and Load Range - Synchronous Buck Converters on Main Outputs - Hysteretic Operation at Light Load.
- No Current-Sense Resistor Required - Uses MOSFET’s rDS(ON) - Optional Current-Sense Resistor for More Precision.
- Operates Directly From Battery 5.6 to 22V Input.
- Input Undervoltage Lock-Out (UVLO).
- Excellent Dynamic Respon.
