The LTC3835IGN-1#PBF is a high performance synchronous step-down switching regulator controller from Analog Devices. It is capable of driving a step-down switching regulator topology and is capable of operating at switching frequencies up to 500kHz. The device has an integrated 5-bit DAC, enabling accurate output voltage setting, as well as having integrated power MOSFETs, allowing for smaller and more efficient designs. It can also operate in a wide input voltage range, from 20V to 36V, making it ideal for automotive or wide input voltage industrial applications. The LTC3835IGN-1#PBF also offers improved performance with higher efficiency and lower output ripple with built-in features such as over-temperature shutdown, output overvoltage protection, cycle-by-cycle current limiting, frequency dithering, and advanced loop compensation techniques.
