A8425 Detalles de producto

Description
The A8425 charges photoflash capacitors for digital cameras, camcorders, and DSC combos. An integrated 55 V DMOS switch drives the transformer in a flyback topology optimized for 2-cell Li+ battery input. An integrated IGBT driver with separate source and sink pins allows high performance red-eye reduction implementation.

Features and Benefits
▪ Wide battery voltage range: 1.5 to 11 V
▪ Integrated 55 V DMOS switch in very thin profile
   3 mm × 3 mm, 0.75 mm nominal height package
▪ Peak current limit continuously adjustable from 1.0 to 3.2 A
▪ Output voltage sensing on primary side: no resistor divider
   required
▪ >75% efficiency
▪ Fast charge time
▪ Charge Complete indication
▪ Flexible, high current IGBT drive
▪ Independent IGBT driver supply
▪ Separate sink and source pins with 6 Ω pull-up and
   20 Ω pull-down
▪ Interlocked trigger pin improves noise immunity
▪ No primary-side Schottky diode needed

Applications include:
▪ SLR camera flash
▪ Digital camcorder/DSC combo flash
▪ 2 Li+ input strobe
