FEATURES DESCRIPTIONS

Over-Current Protection

The modules include an internal output over-current

protection circuit, which will endure current limiting for

an unlimited duration during output overload. If the

output current exceeds the OCP set point, the modules

will automatically shut down (hiccup mode).

The modules will try to restart after 200ms. If the

overload condition still exists, the module will shut down

again. This restart trial will continue until the overload

condition is corrected.

Over-Voltage Protection

The modules include an internal output over-voltage

protection circuit, which monitors the voltage on the

output

terminals.

If

this

voltage

exceeds

the

over-voltage set point, the module will shut down

(Hiccup mode). The modules will try to restart after

200ms. If the fault condition still exists, the module will

shut down again. This restart trial will continue until the

fault condition is corrected.

Over-Temperature Protection

The over-temperature protection consists of circuitry

that provides protection from thermal damage. If the

temperature exceeds the over-temperature threshold

the module will shut down.

The module will try to restart after the module go back to

safe temperature. If the over-temperature condition still

exists during restart, the module will shut down again.

This restart trial will continue until the temperature is

within specification.

Remote On/Off

The remote on/off feature on the module can be either

negative or positive logic. Negative logic turns the

module on during a logic low and off during logic high.

Positive logic turns the modules on during logic high and

off during logic low.

Remote on/off can be controlled by an external switch

between the on/off terminal and the Vi(-) terminal. The

switch can be an open collector or open drain.

For negative logic if the remote on/off feature is not

used, please short the on/off pin to Vi(-). For positive

logic if the remote on/off feature is not used, please

leave the on/off pin floating.

Remote Sense

Remote sense compensates for voltage drops on the

output by sensing the actual output voltage at the point

of load. The voltage between the remote sense pins

and the output terminals must not exceed the output

voltage sense range given here:

[Vo(+) – Vo(–)] – [SENSE(+) – SENSE(–)] ≤ 10% × Vout

This limit includes any increase in voltage due to

remote sense compensation

operation

If the remote sense feature is not used to regulate the

output at the point of load, please connect SENSE(+) to

Vo(+) and SENSE(–) to Vo(–) at the module.

The output voltage can be increased by the remote

sense; When using the remote sense the output voltage

of the module is usually increased, which increases the

power output of the module with the same output

current.

Care should be taken to ensure that the maximum

output power does not exceed the maximum rated

power.
