Note: When contacting these suppliers, please indicate you are using the MAX5037.
Quick Start
The MAX5037 EV kit is fully assembled and tested. The
termination for input, output, and control is provided at
the edge connector as per VRM 9.0 specification. The
MAX5037 EV kit module fits into AMP connector
1364125-1 or equivalent. Follow these steps to verify
board operation. In the quick-start operation, full load
performance cannot be verified.
12V Input Operation
1) Connect a wire from edge-connector pin 57 to
COM. This sets the VID code to 01111 and output
voltage of 1.475V.
2) Place a jumper between pins 2 and 3 of JP4 for
250kHz switching frequency operation.
3) Connect a voltage source (15V/20A, min) at the
input (across C1 or C2). Use heavy-gauge wire,
and keep the connecting wires between the EV kit
and voltage source short. Use 2200μF/16V at the
input if the wires running from the voltage source to
the EV kit are thin and long. Connect voltmeters
across +VIN to COM and +VOUT to COM.
4) Connect the load between +VOUT (edge-connector
pins 49, 50) to COM (edge-connector pins 40, 42),
with ammeter in series; set the load to 1 ? . Connect
the voltmeter between SENSE+ (edge-connector
pin 52) and SENSE- (edge-connector pin 11) to
monitor the output voltage.
5) Gradually increase the input voltage to 12V while
monitoring the output voltage and input current.
5V Input Operation
1) Short the JMPR-5VIN pins with wire on the bottom
layer of the EV kit PC board. This connects IN
(MAX5037 pin 28) and VCC (MAX5037 pin 27)
(Figure 18).
2) Connect a wire from edge-connector pin 57 to
COM. This sets the VID code to 01111 and output
voltage of 1.475V.
3) Place a shunt between pins 2 and 3 of jumper JP4
for 250kHz switching frequency operation. For
500kHz operation, move the shunt to pins 1 and 2
of jumper JP4.
4) Connect a voltage source (range up to 15V/20A) at
the input (across C1 or C2). Use heavy-gauge wire,
and keep the connecting wires between the EV kit
and voltage source short. Use 2200μF/16V at the
input if the wires running from the source to the EV
kit are thin and long. Connect voltmeters across
+VIN to COM and +VOUT to COM.
5) Connect the load between +VOUT (edge-connector
pins 49, 50) to COM (edge-connector pins 40, 42),
with ammeter in series; set the load to 1 ? .
6) Connect the voltmeter between SENSE+ (edge-
connector pin 52) and SENSE- (edge-connector pin
11) to monitor the output voltage.
7) Gradually increase the input voltage to 5V while
monitoring the output voltage and input current.
Caution
1) Do not cover the gold plating of the edge connector
with solder if you want to evaluate the full load oper-
ation using the AMP connector.
2) In case of 5VIN operation, keep the input voltage
below 6V (Refer to the Absolute Maximum Ratings
of the MAX5037 data sheet).
