Test: R
DS(ON)H and RDS(ON)L
1.
Configure the specified test equipment as shown in Figure 8.
2.
Enable UUT by connecting the jumper to the ‘ON’ position, and connect the FB pin to GND to turn-on the
high side PMOS and turn-off the low side NMOS.
3.
Connect 4 wires (Force and Sense) from the Keithley power supply between V
IN and LX node.
Set the
compliance to V
SRC = 40mV at ICOMP = 300mA.
4.
Power up and measure
5.
To measure the R
DS(ON)L, repeat steps 2 through 4 with the FB pin connected to VCC (to turn on the low
side NMOS) and connect the 4 wires (Force and Sense) between LX and GND.
