Simplifying surge and power-fail protection circuits in PLC systems

Simplifying surge and power-fail protection circuits in PLC systems
The Programmable Logic Controller (PLC) system is usually connected to an external DC power supply to provide power to the controller unit, backplane and I/O modules. The input protection circuits are required to protect the PLC from various faults that may occur either on the field or the PLC side.

Buck boost charger with power path for Super Cap

Buck boost charger with power path for Super Cap
According to Texas Instruments, Super Cap is becoming very popular in many applications since its unique feature like more recharge cycle, better transient capacity, simpler charger management and less environment pollution. Typical multi-cell Cap in series requires buck boost topology to charge from empty to full when VIN is below five volts.

Simplify low EMI design with power modules

Simplify low EMI design with power modules
When designing a switching power supply, you may have heard of electromagnetic interference (EMI). More and more applications must pass EMI standards in order for their manufacturers to receive approval for commercial resale. A switching power supply implies that there are electrical switchers inside the device, through which EMI radiates.

Use a low-quiescent-current switcher for high-voltage conversion

Use a low-quiescent-current switcher for high-voltage conversion
Texas Instruments explains that, in battery-operated environments, it’s important to pay attention to quiescent current when designing your power system block diagram. Some applications, such as cordless handheld garden tools, lighting controls and cordless lawnmowers, have low-quiescent-current specifications. These tools operate with a battery pack that has an operating voltage range from 12 to 48V or higher.
