Description

J3

4

LIN

OUT (INPUT)

digital

The pin is connected to LIN pin of MASTERGAN4: the pin can be

used either to monitor the output of the deadtime generator or to force

the input to MASTERGAN4 according to the status of R7 (see table 2)

J4

1,2,3

HV

INPUT power

These three pins are connected to VS pins of MASTERGAN4:

connect high voltage potential to this pin according to MASTERGAN4

recommended values (520V)

J5

1,2,3

OUT

OUTPUT

power

These three pins are connected to OUT pins of MASTERGAN4:

connect the load to this terminal (resonant tanks, transformers,…)

J6

1,2,3

LS_S

POWER

These three pins are connected to SENSE pins of MASTERGAN4: the

board is configured with shorted sense resistor (R15), therefore this

pin can be connected to the reference voltage of high voltage potential

(GND_P)

VCC

INPUT power Board supply voltage: set to a value between 4.5V and 6V

CN1

GH

OUTPUT

To be used with proper MMCX male connector to monitor the GH pin

of MASTERGAN4 with high bandwidth, high voltage differential probes

(optically isolated probes are recommended)

CN2

GL

OUTPUT

To be used with proper MMCX male connector to monitor the GL pin

of MASTERGAN4 with high bandwidth differential probes (optically

isolated probes are recommended)

J2: PWM pin

LIN & HIN are generated by the on-board deadtime generator from a single PWM

signal on J2, PIN 7.

J3: LIN & HIN pin

Direct connection to LIN & HIN MASTERGAN4 pins.

LIN, HIN input range: up to 20 V

The recommended power-on sequence is to turn VCC on first, then apply the HV bus voltage. The recommended

power-off sequence is to turn off the HV bus supply first, then VCC.
