Input Considerations
The input must have a stable low impedance AC source for optimum performance. This can be accomplished with external ceramic
capacitors, tantalum capacitors and/or polymer capacitors. Using low impedance tantalum capacitors requires about 20 µF per amp
and an ESR of 250 mΩ per amp of output current. Tantalum capacitors with a combined value of 150 µF and less than 40mΩ ESR
would be adequate. This can be implemented with (1) 150 µF tantalum capacitors with an ESR less than of 40mΩ. Ceramic capacitors
are also recommended to reduce high frequency ripple on the input.
Output Considerations
To maintain the specified output ripple and transient response, external capacitors must be used. An external 1 µF ceramic capacitor in
parallel with a 10 µF low ESR tantalum capacitor will usually meet the specified performance. Improved performance can be achieved
by using more capacitance. Low ESR polymer capacitors may also be used. Two 100 µF, 9 mΩ or lower ESR capacitors are
recommended.
Safety Information
In order to comply with safety requirements the user must provide a fuse in the unearthed input line. This is to prevent earth being
disconnected in the event of a failure.
The converter must be installed as per guidelines outlined by the various safety approvals if safety agency approval is required for the
overall system. The positive input lead must be provided with a fact acting fuse with a maximum rating of 6 A.
Overtemperature Protection
The device will shut down if it becomes too hot (typically 135 °C - at controller IC). Once the converter cools, it automatically restarts.
This feature does not guarantee the converter won’t be damaged by temperatures above its rating.
Remote On/Off
The SXT6A-3-5SA comes standard with Active LOW Negative On/Off logic, i.e., OPEN or LOW (< 0.4 V) will turn ON the device.
To turn the device OFF, increase the voltage level on the On/Off pin above 2.4 V, as shown in Figure 23, placing the part into low
dissipation sleep mode.
The SXT6A-3-5SA-P comes with Active HIGH Positive On/Off logic, i.e., OPEN or HIGH (>2.4 V) will turn on the device. To turn OFF,
decrease the voltage level on the On/Off pin below 0.4 V.
The signal levels of the On/Off pin input is defined with respect to ground.
