SECO-LVDCDC3064-IGBT-GEVB: 6 - 18 Vdc input isolated IGBT gate driver supply +15 V / -7.5 V / 7.5 V with automotive grade NCV3064 controller

The SECO−LVDCDC−3064−IGBT−GEVB is an isolated supply for
IGBT drivers, providing the necessary stable voltage rails −7.5 V / 15 V
for an efficient switching − as well as an additional 7.5 V rail − over a
wide input voltage range (6 Vdc to 18 Vdc). The converter is
implemented as a primary side regulated flyback, with the feedback
loop signal (1.25 V) realized via an auxiliary winding regulated at 5 V
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 IGBT DC/DC supplies,
provisioning a ready to use plug−in solutions for power applications.
