## Summary of Key Data from the Text

Here's a breakdown of the important information extracted from the provided text, categorized for clarity:

1. Electrical Characteristics & Protection:

️· Input Voltage: Device operates with VCC (input voltage). Lockout occurs below 1.9V with 100mV hysteresis (drops out below 1.8V).
️· Current Limit: Active at all times, protecting against overcurrent in both directions.
️· Soft Start: ~925us startup time, prevents inrush current & overshoot. Triggered by EN pin, thermal shutdown, VCC undervoltage, or power cycle.
️· Thermal Shutdown: Tri-states VSW outputs if die temperature exceeds 170°C. Auto-restart attempt at 160°C.
️· Output Overvoltage: Tri-states VSW outputs if output exceeds 106% of the set voltage.
️· VCC Undervoltage Lockout: Device disables below 1.9V.

2. Performance Characteristics (Graphs & Data):

️· Load Regulation: Efficiency varies with output current (Iout) at different output voltages (Vout = 3.3V, 1.8V, 0.8V).
️· Line Regulation: Efficiency varies with input voltage (Vcc) at a fixed output current.
️· Efficiency: Efficiency charts provided show performance across various input/output voltage and current combinations.
️· Startup Response: Data showing startup time.
