This guide is designed to give the prospective designer an overview of the issues involved in designing switchmode power supplies. It describes the basic operation of the more popular topologies of switching power supplies, their relevant parameters, provides circuit design tips, and information on ...
Because the load is a string of LEDs that are current driven, there is a current sense circuit in each chain, consisting of a sense resistor and OpAmp. The results can be checked by an ADC. What To Do? Switch mode converters are interesting circuits. They are goo...
If so, then after MCU enter deep sleep mode, the GPIO could not wakeup it because GPIO is a power level, not a power supply. 2.Please refer to our reference design(K32W148-EVK) schematics, SWITCH_WAKEUP_B connects to 10K resistor with 3V_LDO. You can also try ...
Full-bridge converter with ZVS: (a) circuit schematics and (b) circuit waveforms. The resonant capacitor is equivalent to the parallel connection of the two capacitors (Cr/2) across the switches. The off-state voltage of the switches will not exceed the input voltage during resonance because ...
When the LATCH pin is set to LOW, the power is cut off. Auto Power Off vs Deep Sleep The auto power off circuit cuts off the power completely. So, there is no power consumption when the microcontroller is not executing any task. In deep sleep mode there is much less power consumpti...
Red Power is not present on the associated circuit, and the power supply alarm is configured. The Power A and Power B LEDs show that power is not present on the switch if the power input drops below the low valid level. The power status LEDs only show that power is present if the ...
In other words, SS in short-channel devices can be restored to 60 mV per decade, and S in the near and above-threshold regimes can be restored to transport mechanism limited STP, as illustrated in the schematics in Fig. 4a, b. The significance of the latter is that it provides an ...

These switch mode power supply (SMPS) devices employ D-CAP2 mode control providing a fast transient response and supporting both low-equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components. The TPS...
