Onsemi NCP3064 | Demoboard SECO-LVDCDC-3064-IGBTGEVB

Beschreibung

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.
