The RSO-123.3D is a DC-to-DC converter designed to provide regulated power in an ultra-small form factor. This design is suitable for applications such as small volume medical/industrial control systems, automotive and battery powered systems. The RSO-123.3D operates as a buck, boost or buck boost converter depending on the voltage difference between the input and output. The useful input voltage range is from 4.5 VDC to 40 VDC, while the regulated output range is from 5 VDC to 30 VDC.

The RSO-123.3D regulates output voltage by switching the input voltage on and off very quickly. The duty cycle of the switch is adjusted precisely according to the output voltage. During each switching cycle, some energy is stored in a magnetic inductor, which is then discharged through the switch again on the next switching cycle. This process is repeated until the output voltage is stabilized. In this way, the voltage gain or voltage loss (depending on the polarity of the input voltage and output voltage) is regulated and the desired output voltage is transformed.

The RSO-123.3D operates over a wide temperature range, making it suitable for use in harsh and demanding environments. It also has extremely low output noise, very high efficiency (up to 94%) and a high power density, making it ideal for applications where space is at a premium. The device also features input/output current monitoring and protection circuitry to ensure safe operation.

In addition to the wide temperature range, RSO-123.3D has an adjustable soft start feature which limits inrush current during power up and a forced PWM mode which eliminates electrical noise. Other features include a low EMI/EMC filter, internal over-temperature protection, independent enable pins for multiple device paralleling, an external synchronization input for noise reduction and integration into the customer’s system.

Overall, the RSO-123.3D is an efficient and compact DC-to-DC converter ideal for a wide variety of applications. Its small size and portability make it the perfect choice for powering portable or wearable devices. The wide input and output voltage range, high efficiency, and low EMI/EMC filter make it well-suited for use in automotive and industrial control systems. With its adjustable soft start, enable pins, and forced PWM mode, the RSO-123.3D can be adapted to meet the specific needs of any application.
