This document introduces a high voltage capacitor charger from Linear Technology Corporation. The charger operates in boundary mode and features high frequency and low power consumption.
This document is a design note (DN405) detailing the use of the LT3750, a current mode flyback controller optimized for controlled current charging. It highlights the device's ability to safely charge various energy storage devices, ranging from large high-voltage capacitors used in photoflash equipment and emergency beacons to smaller capacitors for diagnostic testers.
The LT3750 charges the capacitor in about 0.92 seconds.
Both signals are compatible with voltages as high as 24V.
