Key Features
- Isolated 5 V to 5 V DC-DC converter with 4.5 V to 5.5 V input range and 78% conversion efficiency
- UL, IEC, and EN approved for compliance in industrial, medical, and consumer equipment safety certifications
- SIP-5 through-hole package enabling simple PCB integration for board-level galvanic isolation of sensitive analog circuits
Applications
The RB-0505S provides galvanic isolation between ground planes in industrial sensor interfaces, RS-232/RS-485 transceivers, and analog measurement front ends where noise coupling or ground loop elimination is critical. Its 5 V to 5 V isolated topology simplifies designs powered from a single 5 V rail that require a separate isolated supply for ADC references or gate drivers. Approval to UL, IEC, and EN standards facilitates inclusion in certified industrial and medical equipment designs.

Frequently Asked Questions
What input voltage range does the RB-0505S accept, and how much margin does it allow above and below 5 V?
The RB-0505S accepts input voltages from 4.5 V to 5.5 V, providing 0.5 V of headroom below and above the nominal 5 V supply. This tolerance accommodates typical USB and regulated 5 V rail variations without requiring additional pre-regulation, simplifying system power design.
What conversion efficiency does the RB-0505S achieve, and how does that affect thermal management on a PCB?
The RB-0505S achieves 78% typical power conversion efficiency, meaning that at rated output power approximately 22% is dissipated as heat. For a 1 W output module this corresponds to roughly 280 mW of heat dissipation, which the SIP-5 package handles passively without heatsinks in most 25°C to 70°C ambient operating environments.
For which safety certifications is the RB-0505S approved, and what markets does that enable?
The RB-0505S holds UL, IEC, and EN approvals, covering North American UL-listed equipment, international IEC-regulated products, and European EN-compliant designs. These certifications allow the module to be designed into safety-certified industrial control systems, medical devices requiring reinforced isolation up to 1 kV, and consumer electronics sold in EU and US markets.
