VUN12AD02-KMH EVB GUIDE
●Output Voltage Setting: Scope
■The output voltage can be set by a resistive divider from the output to ground. The resistive divider allows the FB pin to sense a fraction of the output voltage as following figure. The output voltage is set according to the following equation where the reference voltage VFB is typical 0.8V.
●Inductor Peak Current Limit Setting
■The current limit of high-side MOSFET switch is adjustable by an external resistor connected to the RLIM pin. The recommended resistor value is ranging from 42.2kΩ (for typical 4.4A) to 56kΩ (for typical 3.4A). When the inductor current reaches the current limit threshold, the COMP voltage will be clamped to limit the inductor current. Inductor current ripple also should be considered into current limit setting. The current limit value is set according to the following approximate equation:
