Technical coantmesntAsGtill valid Datasheet AS3648 2000mA High Current LED Flash Driver 1 General Description The AS3648 is an inductive high efficient DCDC step up converter with two current sinks.
The DCDC step up converter operates at a fixed frequency of 4MHz and includes soft startup to allow easy integration into noise sensitive RF systems.
The two current sinks can operate in flash / torch / assist (=video) light modes.
The AS3648 includes flash timeout, overvoltage, overtemperature, undervoltage and LED short circuit protection functions.
A TXMASK/TORCH function reduces the flash current in case of parallel operation to the RF power amplifier and avoids a system shutdown.
