Switch Mode Power Supply

DRP024V060W1BA

Overload Protection

The Power Supply is provided with an overload protection (OLP) function which protects the power supply from possible damage caused by excess current. The Power Supply also has an over temperature protection (OTP) in case overload condition persists for an extended duration and is below the overload trigger point but > 100% load.

Typically the overload current (IOL) is > ISURGE (150%) output voltage will start dropping when the power supply reaches max power limit. It will go into bouncing mode when the output reaches UVLO

(under voltage point). The output voltage will recover automatically when the overload condition is removed.

Short Circuit Protection

The Power Supply has a short circuit protection which is in line with the overload protection and activates whenever there is a short across the output voltage. It will go into bouncing mode and recovers automatically when the fault is removed.

Over Temperature Protection

The Power Supply has an over temperature protection (OTP). This is activated when the overload condition persists for an extended duration and the output current is below the overload trigger point but >100% load.

In the event of a higher ambient operating condition at 100% load, the Power Supply will run into OTP when the ambient temperature is > 55°C. When activated, the output voltage will go into bouncing mode until the operating ambient temperature drops to 50°C or output capacity is reduced as recommended in the graph.
