The LT-50 is primarily designed to power 5V incandescent lamp loads for airborne/ground instruments, navigation and other critical electronic systems.The LT-50 converts 28 VDC input to 0-5 VDC output with up to 7.5 A continuous output power, 37.5 W total power.Control circuitry design includes use of a popular PWM controller for voltage regulation and output current limit. Protection circuitry design includes low input voltage shutdown, softstart, high input voltage shutdown, output overvoltage limiting and output short circuit current limiting.
