The LT3479EFE#PBF is a current mode, fixed frequency step-up DC/DC converter from Analog Devices, featuring an internal 3A, 42V switch. It offers high efficiency up to 89% and supports a wide input voltage range of 2.5V to 24V. The device includes a programmable soft-start function for limiting inductor current during start-up and inrush current protection against shorts and line transients.
This converter operates with a switching frequency programmable from 200kHz to 3.5MHz via an external resistor. It is capable of producing both positive and negative output voltages, making it suitable for diverse power management applications. The LT3479EFE#PBF is housed in a thermally enhanced 16-lead TSSOP package with an exposed pad for improved thermal performance.
Key features include a low VCESAT switch (0.3V at 2.5A typical), protection against input short circuits and hot plugging, and adjustable output configuration. The operating temperature range is 0°C to 70°C (TA).
