Jumper configurations: Table 4-2 details the jumper configuration information of the SN6507DGQEVM.
Table 4-2. SN6507DGQEVM Jumper Configurations
Connection Label Function
J3 15 V, 12 V, ADJ. Connect pins 1-2, 2-3, or 5-6 of J3 to select the desired regulated output voltage of either 15
V, 12 V, or a custom value respectively bVOUT_LDO and GND_OUT
J4 +VO_LDO_EN Connect this jumper to enable the regulated output LDO, U1
J5 +VOUT, GND_OUT A surface-mount 3x1 terminal block can be soldered onto this footprint for additional
measurement points of each labelled pad
J6 EN_H, EN_L Connect pins 1-2 of J6 to enable or pins 2-3 of J6 to disable SN6507 respectively. Do not
connect any pins of J6 if enable signals are controlling SN6507 using TP6 or if UVLO is
configured using Ruv1 and Ruv2
J7 NOTE Connect pins 1-2 of J7 to bypass output inductor L1 if duty cycle control is not used.
Disconnect these pins to use output inductor L1 for duty cycle control
J9 Default SR, ADJ. SR Connect pins 1-2 of J9 to use the default switching slew rate of SN6507 or connect pins
2-3 to adjust the slew rate using RSR. If J9 is completely disconnected, SN6507 will use its
default slew rate
J10 1 MHz, ADJ., CLK_IN Connect pins 5-6 of J10 for SN6507 to use the internal 1 MHz clock for switching SW1 and
SW2. Connect pins 3-4 of J10 to use an adjustable clock value based on the resistance of
RCLK. Connect pins 1-2 of J10 to use an external clock input connected to the test point
CLK_IN, described as SYNC Mode in Section 7.4.4 of the SN6507 datasheet.
J12 NOTE Connect pins 1-2 of J12 to bypass output inductor L2 if duty cycle control is not used.
Disconnect these pins to use output inductor L2 for duty cycle control
J13 DC_48%, DC_ADJ. Connect pins 1-2 of J13 to use the default switching duty cycle of SN6507 or connect pins
2-3 to adjust the slew rate using RDC. If J13 is completely disconnected, SN6507 will use its
default switching duty cycle
J14 -VOUT, GND_OUT A surface-mount 3x1 terminal block can be soldered onto this footprint for additional
measurement points of each labelled pad
