... OPERATION DESCRIPTION: CURRENT MODE TOPOLOGY The current mode control method, like the one integrated in the VIPer20/20A uses two control loops - an inner current control loop and an outer loop for voltage control. When the Power MOSFET output transistor is on, the inductor current (primary side of the transformer) is ...

... The converter enters an endless start up cycle, with a start-up duty cycle defined by the ratio of charging current towards discharging when the VIPer20/20A tries to start. This ratio is fixed by design from 2 to 15, which gives a 12% start up duty cycle while the power dissipation at start up is approximately 0 ...

... TRANSCONDUCTANCE ERROR AMPLIFIER The VIPer20/20A includes a transconductance error amplifier. Transconductance Gm is the change in output current (I ) versus change in COMP input voltage (V ). Thus COMP ----------------------- - The output impedance Z at the output of this COMP amplifier (COMP pin) can be defined as: V COMP V COM P 1 -------------------------- - -------- - ...

... VIPer20 VDD - OSC 13V + 10 k VIPer20/SP/DIP - VIPer20A/ASP/ADIP OVER-TEMPERATURE PROTECTION: Over-temperature protection is based on chip temperature sensing. The minimum junction temperature at which over-temperature cut-out occurs is 140ºC while the typical value is 170ºC. The device is automatically restarted when the junction temperature decreases to the restart temperature threshold that is typically 40º ...
