Dan Meeks shares his design idea on edn.com: This Design Idea presents a low power short circuit finder that capitalizes on the ear’s sensitivity to changes in frequency. The heart of the circuit is a voltage-to-frequency converter (based on Linear Tech’s AN45, Figure 13, by Jim Williams), which converts millivolt-level DC voltages to a wide […]

Keith Szolusha@ edn.com writes: In certain dc/dc-converter applications, on-chip, cycle-by-cycle current limit may be insufficient protection to prevent a failure during a short circuit. A nonsynchronous boost converter provides a direct path from the input to the short circuit through the inductor and the catch diode. Regardless of current-limit protection in the IC, when a […]
