High-Isolation DC/DC Converters for Gate Drivers

High-Isolation DC/DC Converters for Gate Drivers

DC/DC converters are often required to provide an isolated asymmetric supply for high-side gate drivers. The simplest (functional) isolation can withstand 1 kVDC for one second. This sounds impressive, but it is often insufficient.

High-side inverters are often floated a few hundred volts with an opto-isolated PWM control, so the gate drivers need an isolated power supply. This isolated supply is typically +15/-9 V for IGBT, +20/-5 V or +15/-3 V for SiC, and +6 V and +9 V for GaN. A typical DC/DC isolation voltage would be at least twice the working voltage, but the high ambient temperature and fast switching edges generated by these high-power transistors additionally stress the insulation barrier.

High Isolation DC/DC Converters from RECOM

RECOM combines the required asymmetric output voltages, high insulation voltage, and low isolation capacitance into one simple DC/DC converter module. Whether IGBT, SiC MOSFET or GaN HEMT, RECOM has the matching drop-in product.

SiC Gate Drivers

Designed for optimal SiC MOSFET performance, RECOM’s RxxP and RA3 series deliver precise asymmetric voltages and high current outputs to power first through third generation WBG devices with efficient, high-speed switching.

GaN Gate Drivers

RECOM’s RP, RxxP06S, and RA3 series DC/DC converters deliver high isolation and low capacitance for optimal GaN transistor switching at +6V, with flexible output options—including split +9V for negative gate drive.

IGBT Gate Drivers

RECOM’s RH, RV, RP, RGZ, RKZ, and RxxP series DC/DC converters simplify IGBT driver design with asymmetric +15V/-9V outputs, replacing dual converters with a single compact solution—available in multiple pin-outs and packages.

SiC Gate Drivers – High Isolated DC/DC Converters

RECOM’s 2W SiC gate driver DC/DC converters (RKZ, RxxP2xx, RA3, and R24C2T25 and R24C2T25/R series) provide reinforced isolation up to 6.4kVDC/1s and the asymmetric voltages required for efficient SiC MOSFET switching. The RxxP22005D and RKZ-xx2005D series supply +20V/-5V for first-generation devices, while the RxxP21503D series provides +15V/-3V for second-generation SiC MOSFETs. The compact R24C2T25 and R24C2T25/R series add programmable asymmetric outputs in space-saving SMD packages, while the SMD-mount RA3 series offers three voltage combinations with higher current capability to maximize switching performance across multiple SiC generations.

GaN Drivers – High Isolated DC/DC Converters

RECOM’s RP-xx06S and RxxP06S DC/DC converters provide +6V with high isolation and low capacitance, making them ideal for high slew-rate GaN transistor drivers. For noisier environments, +9V versions can be split via a Zener to +6V and -3V, ensuring safe negative gate bias at turn-off. The R24C2T25 and R24C2T25/R series introduce compact SMD solutions with programmable asymmetric outputs for precise voltage tailoring in GaN applications. For higher power demands, the SMD-mount RA3 series provides three output options and increased current capability to deliver fast, reliable switching of GaN and other WBG devices.
