The VBSD1-DIP series is a family of isolated DC-DC converters with an output power of 1W. It features a wide input voltage range, high efficiency, single voltage output, and small footprint.
The VBSD1-DIP series is an isolated dc‑dc converter designed for board‑mount local supplies in mixed analog/digital circuits, test equipment, and control applications. It offers a semi‑regulated output that can be followed by external 3‑terminal regulators for additional protection.
The handbook includes detailed electrical specifications, isolation ratings, recommended footprints, and application notes such as minimum load requirements, overload protection methods, and filtering recommendations to ensure reliable performance.
| Output Power | 0.4 W – 1 W |
|---|---|
| Isolation Voltage | 1 kVdc (flash tested for 1 min) |
| Efficiency | up to 80 % |
| Operating Temperature Range | -40 °C to +85 °C |
| Power Density | 0.85 W/cm² |
The minimum output load should be at least 10 % of the full load; the module should never be operated under no‑load conditions.
A self‑recovery fuse in series at the input or a circuit breaker can be used to protect against overload.
The module is flash‑tested for 1 minute at 1000 Vdc isolation voltage.
No heatsink is required for operation.
