II SMT Non-isolated Power Modules:
2.4 – 5.5Vdc input; 0.75Vdc to 3.63Vdc Output; 16A output current
Feature Specifications
Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature
conditions. See Feature Descriptions for additional information.
Parameter
On/Off Signal interface
Device code with Suffix “4” – Positive logic
(On/Off is open collector/drain logic input;
Signal referenced to GND - See feature description
section)
Input High Voltage (Module ON)
Input High Current
Input Low Voltage (Module OFF)
Input Low Current
Device Code with no suffix – Negative Logic
(On/OFF pin is open collector/drain logic input with
external pull-up resistor; signal referenced to GND)
Input High Voltage (Module OFF)
Input High Current
Input Low Voltage (Module ON)

Case 1: On/Off input is set to Logic Low (Module
ON) and then input power is applied (delay from
instant at which V

Case 2: Input power is applied for at least one second
and then the On/Off input is set to logic Low (delay from
instant at which Von/Off=0.3V until Vo=10% of Vo, set)
