A detailed application note titled “Input System Instability” is available on the SynQor website which provides an understanding of why this instability arises, and shows the preferred solution for correcting it. Application Circuits: Figure D below provides a typical circuit diagram which details the input filtering and voltage trimming. Input Filtering and External Capacitance: Figure E below provides a diagram showing the internal input filter components. This filter dramatically reduces input terminal ripple current, which otherwise could exceed the rating of an external electrolytic input capacitor. The recommended external input capacitance is speci- fied in the “Input Characteristics” section. More detailed informa- tion is available in the application note titled “EMI Characteristics” on the SynQor website. 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 Quarter-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.
