PART NUMBER: VBSD1-DIP series
DESCRIPTION: dc-dc converter
description
Designed to convert fixed voltages into an isolated voltage, the VBSD1-DIP series is well suited for providing board-mount local supplies in a wide range of applications, including mixed analog/digital circuits, test & measurement equip., process/machine controls, datacom/telecom fields, etc... The semi-regulated output can be followed by 3-terminal regulators to provide output protection, in addition to output regulation.

PART NUMBER: VBSD1-DIP series
DESCRIPTION: dc-dc converter
APPLICATION NOTES:
- Requirement on output load To ensure this module can operate efficiently and reliably, the minimum output load should not be less than 10% of the full load. Also, this product should never be operated under no load conditions. If the actual output power is too small, please connect a resistor with proper resistance at the output end in parallel to increase the load. - Overload protection Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is to connect a self-recovery fuse in series at the input end or to add a circuit breaker to the circuit. - Recommended circuit If you want to further decrease the input/output ripple, an "LC" filtering network may be connected to the input and output ends of the dc-dc converter, see (Figure 1).
- Output voltage regulation and over-voltage protection circuit The simplest device for output voltage regulation, over-voltage and over-current protection is a linear voltage regulator with overheat protection that is connected to the input or output end in series (Figure 2).

It should also be noted that the inductance and the frequency of the "LC" filtering network should be staggered with the dc-dc frequency to avoid mutual interference. However, the capacitance of the output filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every channel of output, provided that safe and reliable operation is ensured, the recommended capacitance of its filter capacitor see (Table 1).

It is not recommended to connect any external capacitor in the application field with less than a 0.5 watt output.
