## BJT Voltage Divider Bias Design Template

1. Voltage Divider Bias Design Template in Excel Applicable Circuit This Voltage Divider Bias Design Template in Excel will work only on below circuit. This circuit is a Voltage Divider Bias. VCC and VBB are both referenced to the circuit ground. In case VBB is tied to VCC, then the value of VBB is same to VCC.   2.

## Quasi Resonant Flyback Operation Checker and Design Tool – Excel

The operation of a quasi resonant converter is dependent to the primary inductance of the transformer, stray capacitance of the circuit (mostly on the primary switch), reflected voltage to the primary winding during flyback action, turns ratio of the transformer, and the given voltages like input voltage, output voltage, output power and intended frequency of operation.
For a beginner or not technical person, these are too much to handle. It will take time even for a technician or an inexperienced engineer to digest all these. However, you don’t need to extend extra effort anymore. There is already a Quasi resonant flyback operation checker and design tool available.

## NPN Transistor Fixed Bias Circuit Design Template

This circuit configuration of NPN transistor is very useful in electronic switch. It has a guaranteed logic high or low when biased properly. This circuit also is can be used in linear operations or amplifier mode by changing the biasing.

## Tiny 5V 2A DCDC

This is a 5V 2A DCDC that can accept input voltage up to 28V. This tiny 5V 2A DCDC will fit in a small space as its form factor is relatively small. The controller is from Texas instruments that is packed in an SOT-23-6. It has built in synchronous MOSFETs and has very high efficiency. The controller operates in high switching
