RPMH24-1.5-EVM-1 Recom Power

Evaluation platform for RPMH-1.5 Power Modules Features Thermal design considerations included Evaluation Module EMI Class B filter Evaluation Easy evaluation of control, power good, Module sequencing and sensing functions RPMH-1.5-EVM-1 Description The RPMH-1.5-EVM-1 generates a constant output voltage with an output current up to 1.5A from an external DC source. All the functions of the RPMH-1.5 like trimming, sequencing, control, and sensing can be evaluated. Also the behavior in overload or over temperature can be evaluated easily before it is designed in.

To equalize ohmic losses of the filter, remove the resistor at R1, and solder a 0 resistor at R2. 4) Disable the device via R5 The device is preset as normally on. It can be disabled by pulling the CTRL pad to GND. Short R5 to disable the device.
