Our products include the following types of DC-DC converters:
- Linear DC-DC converters — using resistive voltage drop to regulate given output voltages, linear DC-DC converter circuits offer low quiescent current, wide input voltage, low noise, and small packages
- Switching DC-DC converters — offering higher power efficiency, easier thermal management, and transformed output voltages, switching DC-DC converter circuits include buck, boost, and buck boost DC-DC converters
- Isolated DC-DC converters – by separating the input from the output electrically and physically, isolated DC-DC converter circuits are often used to break ground loops
- Non-Isolated DC-DC converters — using the transformer to eliminate the DC path between input and output, non-isolated DC-DC converter circuits include step-up and step-down DC-DC converter ICs. Additionally, advantages of non-isolated DC-DC converters include a smaller design footprint and lower costs
- Step-up (boost) DC-DC converters — boost converter ICs are used to boost the voltage output to greater than the input while stepping down the current. Step-up DC-DC converter circuits are often used in battery power systems and photovoltaic cells
- Step-down (buck) DC-DC converters - used to reduce voltage while drawing less current from input to output, step-down DC-DC converter circuits are widely used in lower power consumption electronic devices
- High-power/high-voltage DC-DC converters – high voltage boost converter ICs feature voltages of > approx. 100 V, high power DC-DC converters deliver uncompromising performance in energy management applications
- High-power/low-voltage DC-DC converters – featuring input voltages of < approx. 30 V and output currents 40 A-1000 A, high-power-low-voltage DC-DC converter ICs deliver uncompromising performance in digital connectivity
- Low-power/low-voltage DC-DC converters – featuring voltages of < approx. 30 V and output currents < 40 A, low-power/low-voltage DC-DC converter ICs deliver uncompromising performance in digital connectivity
DC-DC power converters are electronic circuits used in a broad range of electronic devices and components, often where power is supplied primarily from batteries. This means they are found both in small devices such as smartphones and laptops, as well as part of larger systems in vehicles and industrial machinery.
