DC/DC controller generates positive or negative regulated voltages
The LT3759 operates over a wide input voltage range from 1.6V to 42V and is suited for industrial, automotive, medical and telecom applications, the vendor says. With a programmable and synchronizable operating frequency from 100kHz to 1MHz, designers can choose a wide range of inductors and capacitors to optimize size, performance and cost. The fixed frequency, current-mode control architecture results in stable operation over a wide range of supply and output voltages, and the use of all ceramic capacitors, enables a smaller solution size.
The LT3759 drives an external N-channel MOSFET from an internally regulated 4.75V supply. Additional features include programmable soft-start, an accurate 50mV current sense threshold, programmable undervoltage lockout with hysteresis, and a power good signal along with output overvoltage and overcurrent protection.
The LT3759 is available in thermally enhanced MSOP-12 package with extended and industrial operating junction temperature ranges from -40°C to 125°C. The H-grade version operates over a -40°C to 150°C junction temperature range. For more information, visit www.linear.com/product/LT3759
