... Functional description The controller ICE1HS01G with two gate outputs is specially designed for LLC resonant half-bridge converters. An oscillator with accurately-programmed frequency range is built inside the IC. The two gate signals are obtained by passing the signal out from the oscillator through a divide-by-two flip-flop. Therefore, two signals are of exactly 50% duty cycle and 180 of phase ...

... Feedback voltage Vfb [V] Figure 6 Switching frequency versus V Burst mode operation is also provided by ICE1HS01G. During LLC operation, the feedback signal V continuously monitored. When V , the switching signal will be disabled after a fixed blanking time will then rise decrease due to no switching signal. Once V ...

... If V 0.8V for 1.5ms, the frequency will rise to its maximum level. And vice versa. To sum up, ICE1HS01G will increase the switching frequency to limit the resonant current in case of temporary over-load and will also decrease the switching frequency to its normal value after over-load condition goes away ...
