I am trying to design a laser driver using the L7980A
I am trying to use the L7980A as a current driver for a laser diode. The laser operates with 1.65A at 8.7v. I am aware that the laser needs to carefully controlled, to avoid over-voltage killing the diode. I'm using eDesignSuite, but the design gives...
Help in designing a 600V to 24V, 3A isolated DC-DC converter
I have designed an isolated AC-DC converter, 300 to 590V AC input (400V AC nom) to 24V, 4A output using the L6566-BH Controller in eDesignSuite. Attaching the details herewith.Any further guidance regarding the Design implementation in actual Hardwar...
HAL_UART_Init() bug for more than one UART setting
I am working on a LoRaWAN and GNSS project. I have found one inconsistent operation when try to configure UART1 for GNSS connection. UART2 is used as PRINTF for logging. Procedure to produce bug: Use I-CUBE-LRWAN example as the codebase.Add code fr...
Invalid SPICE model IGBT STGW20NC60VD.
Hi.Now I am composing the model of the device in the program Microcap using SPICE model of IGBT STGW20NC60VD. This transistor has current-voltage characteristics shown Figure 1. But SPICE model of transistor has other different characteristics (Fig. ...
Stability analysis for A6985
I'm trying stability analysis phase margin and gain margin for A6985 on the eDesignSuite.I understand that phase margin and fc are showed in bode plot diagram but gain margin is not displayed.and I cannot estimate it manually due to vertical axis sh...
