2.1 Safety Instructions
WARNING
Hot surface. Contact can cause burns. Do not touch.
WARNING
High currents can be present on the input and output.
2.2 Header Information
J1 – VIN/GND Input and return connections from the input supply to the EVM.
This connector accepts up to 12 AWG wire.
MH1/2 – VIN/GND Alternate input and return connections from the input supply to the EVM.
These holes are sized for M4 or #8 bolts.
J2 – VOUT/GND Input and return connections from the EVM to the load.
This connector accepts up to 12 AWG wire.
MH3/4 – VOUT/GND Alternate input and return connections from the EVM to the load.
These holes are sized for M4 or #8 bolts.
J3 – PG/GND The PG output appears on pin 2 of this header with ground on pin 1.
J4 – SYNC_OUT/GND The SYNC_OUT signal appears on pin 1 of this header with ground on pin 2.
J6 – VOUT SMA Measure the output voltage waveform at this SMA connector.
2.3 Jumper Information
JP1 – EN
EN pin input jumper. Place the supplied jumper across ON and EN to turn on the module. Place the
jumper across OFF and EN to turn off the module.
With the jumper installed across ON and EN, you can create a precise turn-on voltage with R2 and R18.
Keep the value of R2 above 15 kΩ.
JP2 – MODE/SYNC
MODE/SYNC pin input jumper. Place the supplied jumper across PWM and MODE/SYNC to operate the
IC in Forced PWM mode. Place the jumper across PFM/PWM and MODE/SYNC to operate the IC in
PFM/PWM mode. Remove the jumper to apply a synchronization signal on the MODE/SYNC pin.
JP3 – PG Pull-up
PG pin pull-up voltage jumper. Place the supplied jumper on JP3 to connect the PG pin pullup resistor to
VIN. Alternatively, the jumper can be removed and a different voltage can be supplied on pin 1 to pull up
the PG pin to a different level. This externally applied voltage must remain below 6.5 V.
JP4 and JP7 – VSET1 VSET1 setting jumper. Place the supplied jumper on either JP4 and JP7 but not both.
JP5 and JP8 – VSET2 VSET2 setting jumper. Place the supplied jumper on either JP5 and JP8 but not both.
JP6 and JP9 – VSET3 VSET3 setting jumper. Place the supplied jumper on either JP6 and JP9 but not both.
To properly set the start-up voltage, the 3 jumpers for VSETx must be set before VIN is applied. Changing the
jumpers after VIN is applied has no effect.
Before applying VIN, verify that all 3 jumpers are installed: to JP4 or JP7, JP5 or JP8, and JP6 or JP9.
Do not leave the VSETx pins floating.
