Linear Technology LT3750EMS#PBF

Description
Flyback converter designed to rapidly charge large capacitors to a user-adjustable target voltage.
Patented boundary mode control scheme minimizes transition losses and reduces transformer size.
Transformer turns ratio and two external resistors easily adjust the output voltage.
Low 78mV current sense accurately limits peak switch current and maximizes efficiency.
Wide input voltage range (3V to 24V) allows operation from various power sources.
CHARGE pin provides full user control.
DONE pin indicates when the capacitor has reached its programmed value.

Features
Charges any size capacitor.
Easily adjustable output voltage.
Drives high current NMOS FETs.
Primary-side sense eliminates the need for an output voltage divider.
Wide input voltage range (3V to 24V).
Drives gate to Vcc - 2V.
Available in 10-lead MS package.

Applications
Emergency warning beacons.
