Photoflash Capacitor Charger for DSC
General Description
The LD7268A is an ideal charge control IC for flash units
with internal soft start, adjustable charging current and
output voltage. It provides a proprietary charging algorithm,
which charges photoflash capacitor quickly and efficiently.
The LD7268A could operate for constant charging current
mode or the mode with lowering the charging current at
lower battery voltage. As well, a built-in totem pole IGBT
driver can drive IGBT quickly and save the board space.
The LD7268A is available in a space-saving MSOP-10
package and is ideal for DSC flash unit.
