Key Features
- Auto-Track™ Sequencing: Allows the output voltage to accurately track other modules or an external voltage during power up and power down.
- On/Off Inhibit: Active-low input for controlling the output voltage.
- Prebias Start-Up: Ability to start up into an existing output voltage.
- Undervoltage Lockout: Prevents the output from following its own input voltage during power up.
- Output Overcurrent Protection: Nonlatching, auto-reset protection against load faults.
- POLA™ Compatibility: Ensures interoperability with other POLA-compatible modules.
- Soft-Start Power Up: Introduces a short time delay before allowing the output voltage to rise, preventing inrush current issues.
