The LT3420EMS-1 is a DC-DC switching regulator manufactured by LT. This component is designed for efficient power conversion and precise control of switching currents using an adaptive on-time/off-time control scheme.
Key specifications include RoHS3 compliance, a Moisture Sensitivity Level (MSL) of 1 Unlimited, and REACH Unaffected status. The part operates in either a "charging" or "refresh" mode to manage photoflash capacitor charging.
In charging mode, the device provides power to charge the photoflash capacitor. The output voltage is monitored, and charging terminates when the target voltage is reached. The part then enters refresh mode, reducing quiescent current while a user-programmable delay is generated by the refresh timer. After the delay, it re-enters charging mode.
The LT3420EMS-1 can be forced into charging mode by toggling the CHARGE pin. Grounding the CT pin allows the refresh timer to wait indefinitely, requiring manual toggling of the CHARGE pin to re-enter charging mode. The device is suitable for applications requiring controlled charging of photoflash capacitors.
The LT3420EMS-1 is RoHS3 Compliant.
The MSL for the LT3420EMS-1 is 1 Unlimited.
The LT3420EMS-1 is REACH Unaffected.
The LT3420EMS-1 uses an adaptive on-time/off-time control scheme and operates in "charging" or "refresh" modes to manage photoflash capacitor charging.
The refresh timer can be disabled by grounding the CT pin, causing the part to wait indefinitely until the CHARGE pin is toggled.
