SX(T)16A-3-5SA SIP Non-Isolated Power Module

Operating Information

SX(T)16A-3-5SA

Remote On/Off

The SX(T)16A-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 SX(T)16A-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.

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 300 µF and less than 15mΩ ESR

would be adequate. This can be implemented with (3) 100 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 20 A (glass type, rated to

32 V).

Overtemperature Protection

The device will shut down if it becomes too hot (typically 125 °C). Once the converter cools, it automatically restarts. This feature does

not guarantee the converter won’t be damaged by temperatures above its rating.
