The MAX732 current-mode PWM regulator makes a good flash EPROM programmer because of the logic-compatible shutdown control, and because the supply is capable of programming four flash devices simultaneously. When heavily loaded, the MAX732 operates in the continuous-conduction mode, where inductor current never returns to zero. When inductor current is depleted, the LX voltage rings around the level of the input supply voltage. This is caused by the tank circuit, which is formed by the inductor and stray capacitances (windings, diode, MOSFET within the chip, etc.). Maxim, 1992, Applications and Product Highlights, p. 4-7.
