Photo-flash charger minimizes parts count :  10/22/98 EDN-Design Ideas  / (added 2/06) Photo-flash and strobe devices operate by discharging a high-voltage capacitor into a bulb. Charging the capacitor from a battery or other low-voltage source requires a step-up dc/dc converter to boost the voltage, typically to 300V. One way to generate the high voltage is to use a flyback converter. The circuit in Figure 1 provides a simple and reliable way to charge a high-voltage capacitor. The flyback converter performs two functions: It boosts the low-voltage input and provides isolation between the input (battery) and output (high voltage). Its main components are the power transformer; the output diode; the output capacitor; and the MIC3172 controller chip, which combines the switching transistor, voltage regulator, and control logic....
