Pulse introduced its first LLC transformer specifically designed for SiC/GaN device switching. The PMT6709NL delivers 2W of power which can be configured with LLC controllers such as the TI UCC25800-Q1 or the MPS MPQ18913 to provide positive and negative outputs for robust switch on/off. The extended creepage UI5 platform provides 3.75kVrms Hi-Pot isolation voltage in a compact (17.2x11x8.5mm max) SMD platform. This IATF design is compatible with full winding automation to fulfil the requirements of high reliability in automotive applications.
Designed for applications such as inverter motor drives that are driven by high voltage batteries, this platform satisfies the 9.1 mm min creepage requirement of IEC 61558-1 for basic insulation and a working voltage up to 850Vrms, or up to 450Vrms working voltage for applications that require reinforced insulation. A split bobbin is use to keep the interwinding capacitance to less the 2.5pF.
