The TPS92550 Constant Current Buck LED Driver Micro-Module drives maximum 450mA LED current up to 10 LEDsin a single string (maximum 14W). It integrates all the powercomponents including the power inductor. The TPS92550provides a full turn-key , highly efficient solution for wide rangeof single string LED lighting applications with up to 96% powerefficiency. The TPS92550 accepts an input voltage rangingfrom 4.5V to 36V and delivers a highly accurate 350mA LEDcurrent as default.
The LED current is adjustable from 300mAto 450mA by charging a single external resistor.The module operates at constant switching frequency(400kHz) with low Electro Magnetic Interference(EMI) complyingwith EN55015 standard. The module has fast controlloop to realize fine LED current pulse yielding 256–step PWMdimming resolution at 240Hz for general lighting. Protectionfeatures include thermal shutdown, input under-voltage lockout,LED open-circuit and short-circuit protections. TheTPS92550 Micro-Module is available in TO-PMOD 7 pin powerpackage.
