WebMay 6, 2024 · Normally no one (with any experience anyway) would use anything over 50% duty cycle, for a multitude of reasons, not the least of which is mosfet heating . Typically the range is closer to 10 to 30%, with 10% allowing higher current (I believe 10X the device rating ) for a duty cycle of <= 10%. Let's take your post one section at a time: WebCycle-by-cycle current limiting can be implemented by using peak, valley, or average inductor current information to detect the overload condition and limit the duty …
WebHiccup Mode Protection: This protection is usually implemented with cycle-by-cycle peak current limiting along with a cycle count circuit. Hiccup operation is initiated when an overcurrent event is detected. The cycle-by-cycle limiting circuit acts to limit the peak current. Then the cycle count circuit counts the switching cycles. WebMaximum Current Limiting With current limiting, any further increase in load current will cause the output voltage to drop. As an extreme case, when the output is short-circuited, the output voltage will drop to zero. The on duty ratio of the MOSFET for this case is 0% and the on duty ratio for the Schottky diode is 100%. The current ...

WebMay 12, 2024 · Overcurrent protection with cycle-by-cycle current limiting. The current-mode control (CMC) buck converter has become very popular in recent years because of its many advantages. One of the major advantages is its inherent cycle-by-cycle current limiting by merely clamping the COMP voltage. Figure 1 shows the block diagram of a …
WebFeb 2, 2024 · CBC current limit is different than CBC fault. CBC Fault means after a few or several CBC current limit events, latch off and looks like the FAULT_AB with a delay (CBC_MAX_COUNT). Just remove the Dpwm1Regs.DPWMFLTCTRL.bit.CBC_FAULT_EN = 1 and you should see the CBC current limit function as you expect. Regards,
