Abstract:
A system and apparatus to reduce current peaking in notification appliances are described. The apparatus may include a current peaking compensation circuit comprising two or more transistors and one or more capacitors configured to reduce a start-up frequency of a pulse-width modulated signal during a first time period and to add a time constant decaying voltage across a resistor divider network to increase a reference voltage during the first time period. Other embodiments are described and claimed.
