Buck converter current limit
WebFigure 2 shows a typical inductor current of a buck converter during normal and overload conditions for the peak current-limiting scheme. During overload condition, as illustrated by I LIMIT, the switching cycle is terminated when the peak current detected is greater than the predetermined threshold. WebThe LM2673 series also has built-in thermal shutdown and resistor programmable current limit of the power MOSFET switch to protect the device and load circuitry under fault …
Buck converter current limit
Did you know?
WebDC conversions from high input voltages to low output voltages, the buck converter must be able to operate down to very short on-timedurations. ... which limits the peaks of the inductor current, low side current sensing only limits the current during the converter off-timewhen inductor current is falling. Therefore in a typical current limit plot WebThis limits the minimum switch ON time and can limit the minimum duty cycle (duty cycle= V OUT / V IN) and maximum converter step-down ratio. Note in the high side configuration, the current signal can be riding on top of a very large common mode voltage (V IN ). Buck Regulator Low Side Placement
