Other Parts Discussed in Thread: LM2576HV,
Hi all,
I want to use an LM5085 in order to supply with power a 6V servo and from the 6V through a linear regulator some 3.3V ICs (including a microcontroller, a SN65HVD11DR RS-485 transceiver and an INA180B4 for sensing if the servo is stalling thus cutting its PWM), with Vin of 48V. The problem is I don't know which servo is going to be finally selected (probably I will not be the one to suggest which one) so I need to support servos that their running and stalling currents might be in a very wide range. For example for a SAVOX servo (SC-0251MG) that I was given for testing, the stall current is 3.5A@6V while for a similar torque servo from Feetech the stall current is 1.5A@6V which in the Feetech case I would be able to use an LM2576HV from you SIMPLE SWITCHER series with 3A maximum current and with lower external components count. I found that your LM5085 with the external MOSFET is probably the best solution as per both the BOM/final cost and the non yet known current specifications. My question is, would the LM5085 be up for the job or should I be looking in something else, especially when having an inductive load that might create over-current spikes?
Thank you
