PQ60050EKX10 Datasheet, PDF (14/15 Pages) SynQor Worldwide Headquarters – TUV certified to EN60950-1

Technical Specification
Input: 35-75V
Output: 5V
Current: 10A
Part No.: PQ60050EKx10
Figure F shows three turn-on scenarios, where a Startup Inhibit
Period is initiated at t₀, t₁, and t₂:
Before time t₀, when the input voltage is below the UVL threshold,
the unit is disabled by the Input Under-Voltage Lockout feature.
When the input voltage rises above the UVL threshold, the
Input Under-Voltage Lockout is released, and a Startup Inhibit
Period is initiated. At the end of this delay, the ON/OFF pin is
evaluated, and since it is active, the unit turns on.
At time t₁, the unit is disabled by the ON/OFF pin, and it cannot
be enabled again until the Startup Inhibit Period has elapsed.
When the ON/OFF pin goes high after t₂, the Startup Inhibit
Period has elapsed, and the output turns on within the typical
Turn-On Time.
