Design suggestions are presented that can be used when designing switching power supply circuitry that is efficient, reliable and easy to test and manufacture. The design hints given serve to limit inrush current, guide the input capacitor selection, improve efficiency, implement output current limiting, provide external synchronization capability, furnish current sharing, and add output
