The ultra-low isolation capacitance, less than 3.5pF, ensures minimal noise propagation across the isolation barrier. All of these exceptional features are packaged in a compact 7.5 x 12.83mm SMD form factor, making it an ideal choice for all isolated gate bias voltage needs.
R24C2T25 - Benefits & Features
Space Efficiency
SMT DC/DC converters are typically smaller in size, allowing for a more compact design. This is crucial in applications where board space is limited, such as in portable devices or miniaturized electronics.
High-Power Density
Surface mount packages contribute to higher power density on the PCB, enabling the creation of more powerful converters within a given space.
Improved Thermal Performance
Surface mount packages contribute to higher power density on the PCB, enabling the creation of more powerful converters within a given space.
Enhanced high-frequency performance
SMT technology reduces lead lengths and parasitic effects, contributing to improved high-frequency performance of the converter. This is beneficial for applications where fast switching speeds are required.
Automated assembly
Surface mount technology supports automated assembly processes, making the production of DC/DC converters more efficient and cost-effective.
Reduced electromagnetic interference (EMI)
SMT components, with their shorter leads and compact layout, can help minimize electromagnetic interference, improving the overall electromagnetic compatibility (EMC) of the system.
Higher component density
MT packages allow for higher component density on the PCB, enabling the integration of additional features or functions into the same space.
R24C2T25 - Isolated DC/DC Converter
Isolation of the R24C2T25 is 3kVAC/1min with an ultra-low coupling capacitance of 3.5pF and a common mode transient immunity of +/-150kV/µs. This makes the parts ideal for powering high-side gate drives with fast dV/dt and dI/dt power switch edge rates.
The R24C2T25 features soft start, input under-voltage and over-voltage lockout, thermal shutdown, and output over-power protection. Output over-voltage and under-voltage lockout are also provided to ensure power devices cannot be stressed by invalid gate voltages. A power-good signal is provided along with ON/OFF control to put the device into standby mode with less than 700µA current draw.
In addition to programmability, the R24C2T25 features another advance compared to its predecessors: the use of surface mount technology (SMT) in the form of a compact 7.5 x 12.83mm 36-pin SSO-package. A surface mount package is highly desired by designers because it offers numerous advantages versus equivalent through-hole devices:
