CRE1S0505SC

DC DC Converters are often used in situations when power requirements or space constraints necessitate the conversion from one type of DC power to another. The CRE1S0505SC is an example of such a DC DC converter, and is intended for applications such as aerospace, defense, instrumentation, power supplies, and general purpose applications. Its characteristics make it particularly suitable for use in systems where the output power is dependent on the input voltage.The CRE1S0505SC is a molded encapsulated DC DC converter with an input/output isolation of 5500 VDC RMS. It is a 4-quadrant buck-boost converter that is capable of both buck and boost operating modes. The input voltage range is from 5 to 48 VDC, and the output voltage is adjustable from 1.6 to 54 VDC. It has a maximum output current of 0.5 A and excellent line and load regulation, with a typical input/output differential voltage of 1.5 V.The CRE1S0505SC is a synchronous buck-boost converter that maintains high efficiency at all load levels. It is designed to achieve a conversion efficiency of up to 91%, with a typical no-load loss of less than 100mW. The converter also has integrated protection features, such as over-current, over-voltage, and over-temperature protection, as well as a power-ok signal to provide status information about the output.In operation, the CRE1S0505SC switches between buck and boost modes to maintain the desired output voltage regardless of the input voltage. When the output voltage is higher than the input voltage, the device operates in buck mode, which results in a power transfer from the output to the input. Conversely, when the output is lower than the input voltage, the device operates in boost mode, resulting in a power transfer from the input to the output.The CRE1S0505SC also features pulse-width modulation (PWM) control techniques for regulation of its output voltage. This technique utilizes a PWM control signal, which is generated by comparing the feedback signal to the reference voltage. The CRE1S0505SC then adjusts the overlap of the two PWM switches to control the output voltage.Overall, the CRE1S0505SC is an ideal choice for applications where efficient operation, space constraints, and power requirements are paramount. The device is highly efficient yet compact, with a low power dissipation in both buck and boost modes. It is designed to provide excellent output voltage regulation with minimum ripple and excellent line and load regulation even under extreme conditions. Additionally, the protection features ensure reliable operation by preventing damage in the event of an over-current, over-voltage, or over-temperature condition.
