APPLICATION CONSIDERATIONS
Input System Instability: This condition can occur because
any DC/DC converter appears incrementally as a negative
resistance load. A detailed application note titled “Input
System Instability” is available on the SynQor website which
provides an understanding of why this instability arises, and
shows the preferred solution for correcting it.
Application Circuits: Figure D below provides a typical cir-
cuit diagram which details the input filtering and voltage trim-
ming.
Input Filtering and External Input Capacitance: Figure E
below shows the internal input filter components. This filter dra-
matically reduces input terminal ripple current, which otherwise
could exceed the rating of an external electrolytic input capaci-
tor. The recommended external input capacitance is specified in
the “Input Characteristics” section on the Electrical Specifications
page. More detailed information is available in the application
note titled “EMI Characteristics” on the SynQor website.
Output Filtering and External Output Capacitance:
Figure E below shows the internal output filter components. This
filter dramatically reduces output voltage ripple. However, some
minimum external output capacitance is required, as specified in
the Output Characteristics section on the Electrical Specifications
page. No damage will occur without this capacitor connected,
but peak output voltage ripple will be much higher.
RoHS Compliance: The EU led RoHS (Restriction of Hazardous
Substances) Directive bans the use of Lead, Cadmium,
Hexavalent Chromium, Mercury, Polybrominated Biphenyls
(PBB), and Polybrominated Diphenyl Ether (PBDE) in Electrical
and Electronic Equipment. This SynQor product is available as
5/6 RoHS compliant (product with lead) or 6/6 RoHS compliant.
For more information please refer to SynQor’s RoHS addendum
available at our RoHS Compliance / Lead Free Initiative web
page or e-mail us at rohs@synqor.com.
