PQ60150EGL05 Datasheet, PDF (12/13 Pages) SynQor Worldwide Headquarters – Eighth-brick DC/DC Converter

Technical Specification
Input: 35-75 V
Output: 15 V
Current: 5 A
Package: Eighth-brick
Startup Inhibit Period: The Startup Inhibit Period ensures that
the converter will remain off for approximately 200ms when it is
shut down for any reason. When an output short is present, this
generates a 5Hz "hiccup mode," which prevents the converter
from overheating. In all, there are seven ways that the converter
can be shut down, initiating a Startup Inhibit Period:
• Input Under-Voltage Lockout
• Input Over-Voltage Shutdown (not present in Eighth-brick)
• Output Over-Voltage Protection
• Over Temperature Shutdown
• Current Limit
• Short Circuit Protection
• Turned off by the ON/OFF input
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.
RoHS Compliance: The EU led RoHS (Restriction of Hazardous
Substances) Directive bans the use of Lead, Cadmium,
Hexavalent Chromium, Mercury, Polybrominated Biphenyls
(PBB), and Polybrominated Diphenyl Ether (PBDE) in Electrical
and Electronic Equipment. This SynQor product is available as
5/6 RoHS compliant (product with lead) or 6/6 RoHS compliant.
