AS3630
8A Supercap Flash Driver
General Description
Figure AS3630 – 1: Key Benefits and Features
The AS3630 is an inductive high efficient 4MHz dual DCDC step up converter with several sources. It supports the charging of a Supercap, its voltage balancing and a highly efficient DCDC step up from the Supercap to the LED and from VIN to the LED to power the flash LED with up to 8A. The AS3630 supports the pre-charging of the Supercap (to VIN) to reduce the startup time for the flash without reducing the lifetime of the Supercap.
The system concept supports an immediate torch function without first charging the Supercap.
The AS3630 includes flash timeout, over- undervoltage, overtemperature and LED short circuit protection.
