Step 2: Assign a Test Point Manually The general rule of test points on a printed circuit board is that each net needs to have a probeable point to test. These “test points” need to be known and cataloged in the Printed Circuit Board design system for reports to be generated that th...
Programmable DC loads are an absolute necessity if you want to test a power supply. To that end, we acquired two high precision Maynuo M9714 1200 Watt and two Maynuo M9711 150 Watt electronic loads, which will allow us to draw up to 2400 Watts from 12 Volt lines and up to 150 Watts ...
RESERVED . Immediate The PFC UVP shall be set to "Immediate": the device shuts down the power supply if the PFC UVP is triggered. In this case the un-latch timer depends on the NVM parameter PFC UVP auto-restart timer (see 3.2.11). Please remember that because of the...
SMPS is the acronym of the word Switch Mode Power Supply. The name clearly suggests that the concept has something or entirely to do with pulses or switching of the employed devices. I have explained how SMPS adapters work for converting mains voltage to a lower DC voltage. Advantage of SMPS...
Error = 0x4D9 – 0x4CA = 15 LSB 14/53 AN2834 Rev 10 AN2834 ADC errors 3.2.2 The SMPS (switch-mode power supply) usually embeds internal fast-switching power transistors. This introduces high-frequency noise in the output. The switching noise is in the range of 15 kHz to 1 ...
The most common application for an isolation transformer is to isolate a device from the AC line ground. As an example of why this may be necessary, consider the switched mode power supply (SMPS). A typical line powered SMPS presents several safety related concerns (Figure 7). Figure 7: ...
In this post we try to diagnose a burnt SMPS circuit and try to troubleshoot and repair the circuit. The shown unit is a cheap readymade Chinese make SMPS

Before we move on to recommended solutions, I want to explain the primary reasons why EMI is created by a wired internet system: Modems and routers all have a switched-mode power supply (SMPS) that is plugged into an outlet. The EMI created by this SMPS can travel along your electrical ...
Default template value is the following: #define IS_TCXO_SUPPORTED 1U 4.5 Power regulation Depending on the user application, a LDO or an SMPS (also named DC/DC) is used for power regulation. An SMPS is used on the STM32WL55 Nucleo boards. Table 7. BSP radio SMPS Function u...
