## Design Template for NMOS Lowside Relay Driver

How the Design Template Works The template will work with the given circuit below. All the fields in orange are inputs. Which means the user should provide values on it. On the other hand, all the fields in green are computation results with the formula. These must not be altered. Otherwise, the template will result to error.

## Synchronous Buck Converter Excel Design Template

Buck converter design is never easy. There are lots to consider ensuring a robust design. The components must be selected well and ensure sufficient design margins. However, this is difficult no more with the use of this synchronous buck converter excel design template. This design template is made in excel format. Thus everyone can use this. This is very handy

## BJT Voltage Divider Bias Design Template

BJT Voltage Divider Bias Design Template – Mathcad This design template comes in two formats. First is in Mathcad and the second one is in excel. The equations are derived in Mathcad. This is all you need to design such circuit. No need to go back to basics and perform research again on how to derive equations. It is all

## 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 Fixed Bias 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.

## 3 Outputs Discontinuous Flyback Converter Design Template-Mathcad

This is Mathcad template to design a 3 outputs discontinuous flyback converter. All are fully automated. All you need to do is to follow the instructions and and the end you will get the values needed to design a working flyback converter with 3 outputs.

## 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
