PQ60033ETL30 Datasheet, PDF (12/13 Pages) SynQor Worldwide Headquarters – Eighth-brick DC/DC Converter
Technical Specification
Input: 35-75 V
Output: 3.3 V
Current: 30 A
Package: Eighth-brick
At time t1, the input voltage falls below the Input Under-Voltage
Lockout threshold. This disables the unit and initiates a Restart
Inhibit Period. During the Restart Inhibit Period, if the input volt-
age again exceeds the UVLO threshold, the unit cannot be
enabled again until the Restart Inhibit Period has elapsed. Once
this occurs, the output turns on with the Typical Turn-On Time.
At time t2, the ON/OFF pin disables the unit and initiates a
Restart Inhibit Period. During the Restart Inhibit Period, if the
ON/OFF pin is again activated, the unit cannot be enabled
again until the Restart Inhibit Period has elapsed. Once this
occurs, the output turns on with the Typical Turn-On Time.
When the ON/OFF pin goes high after t3, and the Restart Inhibit
Period has elapsed, the output turns on approximately 1.6ms
after the ON/OFF pin is activated, with the Typical Turn-On Time.
If the Under-Voltage Lockout threshold has not been satisfied at
the end of either Inhibit Period, the unit will remain disabled until
the input voltage exceeds the UVLO threshold. Once this occurs,
the output turns on with the Typical Turn-On Time.
If the ON/OFF pin is activated after either Inhibit Period has
elapsed, the output will turn on approximately 1.6ms after the
ON/OFF pin is activated, with the Typical Turn-On Time.
