The LT3468ES5-1 is a highly integrated step-up DC/DC converter designed specifically for charging photoflash capacitors in digital and film cameras. Manufactured by Linear Technology, now part of Analog Devices, this compact and efficient device is housed in a small TSOT-23 package, making it an ideal choice for space-constrained applications.

The LT3468ES5-1 features a fixed-frequency, current-mode architecture with a built-in power switch, which allows for a minimal external component count and simplifies the circuit design. With its wide input voltage range of 2.7V to 16V, it can operate from a variety of power sources, including single-cell lithium-ion batteries, making it versatile for different camera designs.

This charger is capable of delivering output voltages up to 40V, which is necessary for quickly charging high-voltage photoflash capacitors. The LT3468ES5-1 also includes a high-voltage switch with a 1.2A current limit, which ensures safe operation during the charging cycle. Additionally, the device features an automatic power-down function when charging is complete, which helps to conserve battery life in portable devices.

Other notable features of the LT3468ES5-1 include its low shutdown current (

With its high level of integration and performance, the LT3468ES5-1 is an excellent choice for designers looking for a compact, efficient, and reliable solution for photoflash capacitor charging. Its ease of use and comprehensive feature set ensure that it can meet the requirements of even the most demanding photoflash applications.
