PART NUMBER: VBSD1-SIP Series
DESCRIPTION: dc-dc converter
Minimum loading converter needs minimum loading maintain output regulation. Operation under no-load conditions will cause immediate damages reduce reliability, cause performance meet specifications. Regulation With semi-regulated design, converter's output voltage varies with load current will change proportionally input voltage. regulated output needed, external regulator used shown Figure
APPLICATION NOTES:
Input filtering reduce reflected ripple current minimize EMI, especially when converter input more than away from source, recommended connect electrolytic capacitor between Gnd. values suggested shown Table additional filtering required, capacitance increased, expanded network shown Figure

Input Voltage 3.3,
Output filtering output capacitor needed meet output ripple requirements shown Table 2.Output capacitance increased additional filtering, should exeed expanded network Figure
Protection
External Input Capacitance
converter minimal protection against input overvoltage output over-load, permanently damaged exposed these conditions. input clamping device used input voltage limiting. input fuse output fuse also used protect against over-loading. Dual outputs used single output +Vout -Vout used obtain single output that outputs. this case, shouldn't used. External Regulator external 3-terminal regulator connected output converter achieve full regulation. Make sure converter's output voltage provides sufficient head room regulator. additional benefit that built-in protection features regulator, such OCP, OTP, etc, will protect converter also. complimentory supply, negative output regulator must used achieve negative regulated output.
