That is it; this is how you can design your own12v SMPS circuit. Once you have understood the working, you can alter the12v SMPS circuit diagramto suit for your voltage and power requirements. Hope you understood the tutorial and enjoyed learning something useful. If you have any questions ...

From the circuit diagram above, it indicates that the grounding for the CoolSET™ can be split into several groups; signal ground, VCC ground, Current sense resistor ground and EMI return ground. All the split grounds should be connected to the bulk capacitor ground separately. Signal grou...

This is done by blanking the triggering block of the ZCD circuit as mentioned before. The duration of the blanking time (3.5µs min.) is a function of the error amplifier output VCOMP, as shown in the diagram of figure 6. If the load current and the input voltage are such that the...
( having wattage equal to my circuit total power drawn from my all 4 voltages ) then i will use LDO /Charge pump to get +/-5V & boost converter to get +/-12V. will it work if so please help me out to design smps having two output. 1. +10v / 3A = 30 W ( Main output from...

A bootstrap capacitor is required to supply the gate drive circuit of the high-side NMOS. The output voltage is configurable by OTP from 3.3 V to 5.2 V using the VPREV_OTP [5:0] bit field (CFG_ VPRE_ 1_OTP register), and the switching frequency is configurable by OTP using the V...
Some time ago I powered a PIC uC with the typical application circuit of the LNK302PN from Power Integrations as shown in the attached schematic. NO GALVANIC ISOLATION. I blew the laptop and the PICKit3 when attempting to program the uC. Lesson learned!Later... I was given a no name ...
As can be seen from Figure 1b, the port VIN provides a voltage input to the DC1379B, which is stepped down by the LTM8025 and filtered by the peripheral circuit, and is output from the port VOUT to the downstream load. Figure 1. Board diagram and schematic of DC1379B [29]. (a)...
