    Specifications and features

    - Low start-up current (<1mA)

    - Automatic feed forward compensation

    - Trimmed oscillator discharge current

    - Pulse-by-pulse current limiting

    - Enhanced load response characteristics

    - Under-voltage lockout with 6V hysteresis (SG1844 only)

    - Double pulse suppression

    - High-current totem-pole output

    - Internally trimmed bandgap reference

    - 500kHz operation

    - Undervoltage lockout SG1844 - 16 volts SG1845 - 8.4 volts

    - Low shoot-through current <75mA over temperature

    Application Scenarios
