LTC3114EDHC-1#TRPBF Analog Devices

The LTC3114EDHC-1#TRPBF is a 40V, 1A synchronous buck-boost switching voltage regulator with programmable current limit manufactured by Analog Devices. This device is intended to provide a programmable output voltage in applications that require a wide input-to-output voltage range and the capability to limit current to the load. The LTC3114EDHC-1#TRPBF is capable of bucking or boosting a regulated output anywhere in its 40V input range, from 0.8V up to 38V, with a maximum output current of 1A and a programmable current limit setting of up to 500mA. Additionally, the device has an adjustable switching frequency of 200kHz to 2.2MHz which allows for better noise control at higher frequencies and power efficiency at lower frequencies. Other features include a soft-start section for adjustable rising time and a peak current limit section to improve start-up performance and protect the device from over-current conditions. Finally, the device has built-in protection against short-circuits, over-voltage, and under-voltage.
