SECO-LVDCDC3064-SIC-GEVB

SECO−LVDCDC3064−SIC−GEVB is an isolated supply for SiC drivers, providing the necessary stable voltage rails −5V / 20V for an efficient switching − as well as an additional 5V rail − over a wide input voltage range (6VDCto 18VDC). The converter is implemented as a primary side regulated flyback, with the feedback loop signal (1.25V) realized via an auxiliary winding regulated at 5V and a voltage divider. The design leverages the several merits of the NCV3064 regulator, enabling a low component count, compact and robust design. Among the features of this converter stand out – e.g. an internal temperature compensated reference, a controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. The board is realized with Automotive qualified parts and is pin compatible with commercial SiC DC/DC supplies, provisioning a ready to use plug−in solutions for power applications.
