General Description
The AT1450 is a single-channel PWM control IC for Photoflash capacitor charger with soft start function and auto-discharge circuit. Adjustable soft start is programmed with an external capacitor on SS pin.
FEATUREs
• 2.5 to 13 V supply voltage operating range.
• Low current consumption: 6 mA in operation,
• 20 kHz to 1 MHz operation frequency range.
• Provides a fixed output current with minimal
supply voltage fluctuations by using an external
resistor to set the output current.
• Totem-pole output.
• Built-in soft start circuit.
• Built-in auto-discharge function.
APPLICATIONs
• Digital Still Cameras flash unit
