The converter offers a high efficiency of up to 96% and is able to operate at frequencies of up to 1MHz and power levels of up to 15W. It is ideal for applications such as automotive accessories, button batteries, base stations and IoT.

Application Field

The IMM0212D05 is targeted for use in automotive, consumer and industrial applications. It is a very versatile DC-DC converter that can be used for a wide range of applications. Some of the highlighted applications include automotive accessories, button batteries, base stations and other Internet of Things applications.

Working Principle

The IMM0212D05 is a highly efficient two-phase synchronous buck-boost DC-DC converter. It utilizes two phases, allowing for high efficiency and output power along with minimal switching losses. The two phase architecture provides an even power delivery and faster transient response, resulting in less noise and higher output current capability. It also provides a smooth transition between different voltage regulation points, allowing for a wide input voltage range and stable output.The IMM0212D05 operates at frequencies of up to 1MHz, providing a high level of efficiency. The converter utilizes a pulse width modulation (PWM) modulation scheme, with a pre-compensation circuit to ensure low output voltage ripple and fast response to load changes.The rectifier at the input section converts the AC input to DC voltage, while the transformer isolates the output from the input section. An inverter is then used to convert the DC input voltage into an AC voltage, which is then used to drive two opposite polarity switches. These switches are driven by their complementary signals, which are generated from an internal logic.In order to minimize losses, the converter utilizes synchronous rectification at the output section, where the output is rectified by switching the current path between the switches and the power source. In addition, the IMM0212D05 is equipped with an intelligent protection circuit to prevent the converter from any possible overvoltage or overcurrent conditions.

Conclusion

The IMM0212D05 DC-DC converter from Infineon provides high efficiency and low losses at wide input voltage range due to its two phase boost converters design. It is ideal for applications such as automotive accessories, button batteries, base stations and IoT. The converter operates at frequencies of up to 1MHz and provides an output voltage of 8.2V. It also utilizes an intelligent protection circuit to prevent the converter from any possible overvoltage or overcurrent conditions.
