DC/DC converters are often required to provide an isolated asymmetric supply for high-side gate drivers. The simplest (functional) isolation can withstand 1kVDC for one second. This sounds impressive; however this is often not sufficient. High side inverters are often floated a few hundred volts with an opto-isolated PWM control, so the gate drivers need
RECOM's R-REF01-HB consists of a half-bridge suitable for voltages up to 1kV and a fully-isolated driver stage with isolated power supplies for the low-side and the high-side switching transistors. It is suitable for single gate drive supply voltages as low as +4V as well as dual gate drive supply voltages as high as +20V /
High slew-rate GaN transistors require an isolated 6V supply with high isolation voltage and low isolation capacitance. The RxxP06S and RP-xx06X series have been designed to fulfill this demanding requirement. The internal transformers in both series use a pot-core to physically separate the input and output windings, however the converters still fit into an
The RxxPxxyyD Series devices feature 6400 VDC isolation and <10 pF isolation capacitance and have been designed to fulfill the demanding requirements of high slew-rate SiC transistor drivers. These new DC/DC converters can be used with equal power (1W + 1W) or equal current (1.6W + 0.4W) driver applications, as the dual outputs feature
