Hi,
My name is John Lester Soronio. I am a senior power supply and charger design engineer and currently working as project lead of many power solutions released in the market involving AC-DC power supply, DC-DC power supply, DC-DC converter (buck, boost, buck-boost, flyback, forward, resonance, etc), chargers and adapters. I am in this business for more than 10 years. I am working full time at Artesyn Embedded Technologies; formerly Emerson Network Power.
Summary of Capabilities:
1. Schematic design using Eagle CAD and PCB layout
2. AC-DC power supply design, switching and linear, multiple outputs or single, trimmable or fixed
3. DC-DC power supply design, boost, buck, buck-boost, etc...
4. Offline AC-DC adapter design
5. Charger design with constant current and constant voltage, AC-DC for phones and other applications
6. Charger design with constant current and constant voltage , DC-DC for Li-Ion, Li-Poly, LiFeP04, Lead acid and so on
7. LED lighting related applications
8. Solar panel energy harvesting and charging systems
9. Switching converters such as buck, boost, buck-boost, flyback, forward, LLC, half bridge etc
10. Amplifiers, filters, switch
11. MCU, DSP and digital circuits
12. Schematic and PCB using eagle
