Technical Reference Notes
ALQ25 Series
(Open Frame Single Output Quarter Brick)
MODEL: ALQ25 SERIES
Dec 1, 2003 - REVISION B
SHEET 10 OF 15
OUTPUT ENABLE
The ALQ25 series comes with an ENABLE pin (PIN 2), which is primarily used to turn ON/OFF the converter. Both a
Positive (no part number suffix required) and a Negative (suffix “N” required) Enable Logic options are being offered. Please
refer to Table 2 for the Part Numbering Scheme.
For Positive Enable, the converter is turned on when the ENABLE pin is at logic HIGH or left open. The unit turns off when
the ENABLE pin is at logic LOW or directly connected to -V
IN
. On the other hand, the Negative Enable version turns unit on
when the ENABLE pin is at logic LOW or directly connected to -V
IN
. The unit turns off when the ENABLE pin is at Logic
HIGH.
OUTPUT OVER VOLTAGE PROTECTION (OVP)
The Over-Voltage Protection consists of circuitry that monitors the voltage on the output terminals. If the output voltage
exceeds the Over Voltage Protection threshold limit, module will work on intermittent model. When the Over Voltage
condition is removed, the module will automatically restart.
The protection mechanism is such that the unit can continue in this condition until the fault is cleared.
OVER CURRENT PROTECTION (OCP)
The Over Current Protection circuit comes in latching mode. The converter is latched off if the load current on the output
reaches the OCP threshold limit. The OCP latch can be reset either by cycling the input voltage or toggling the Enable signal
for 100ms. Consult factory for Auto-restart option.
The Over Current Protection (OCP) circuit comes in foldback current limit. If output current exceed the OCP threshold limit,
or at a short circuit condition, the module will work on intermittent model. When the Over Current condition is removed, the
module will automatically restart.
OVER TEMPERATURE PROTECTION (OTP)
These modules feature an over-temperature protection circuit to safeguard against thermal damage. The module will work on
intermittent mode when the maximum device reference temperature is exceeded. When the over-temperature condition is
removed, the converter will automatically restart
