UP6007 4 UP6007-ds-p0000, apr . 2015 www .upi-se mi.com functional description the UP6007 is a compa ct high-ef f iciency ste p-up converter with integrated switch specifically designed to drive up to white leds in series. series connection of the leds provides identical led current resulting in uniform brightness. fixed 1mhz/500khz operation allows smallest output ri pple a nd extern al component size. w ith high conversion ef f iciency a nd small pa ck age, the UP6007 is suitable for portable devices where pcb area is especially concerned. power on reset the UP6007 continuously monitors supply input voltage at vin pin for power on reset (por). once the rising por thre shold is exceeded, the UP6007 sets itsel f to a ctive state a nd is re a dy to a cce pt chi p en a ble comma nd. the por threshold is typically 2.5v at vin rising with 0.1v hysteresis. enable/disable pulling the en pin higher tha n 1.6v en a ble s the device a nd initi ate s its soft start cycle. pulling the en pin lower tha n 0.8v disa ble s the device a nd reduce s its shutdown current le ss tha n 1ua typically . when the en pin pulls low , the UP6007 does not shuts down immediately but reduces the led current gra dually . soft start the UP6007 limits the in-rush current at start-up by incre a sing the current li mit. this prevents unwa nted shutdown otherwise may be triggered by voltage drop due to large inrush current. led current regulation the UP6007 operate s in a con sta nt-frequency , slope- compen sated pe a k-current-mode control to regulate the led current. the led current is sensed at fb pin by a current sensing resistor (r fb ): v fb = r fb x iled. the error a mplif ier compare s the feedba ck voltage with intern al 0.2v reference a nd compen sate s the error sign al to get current comma nd level. the intern al nmosfet turn s on at the beginning of e a ch switching cycle a nd lets the inductor current ra mp up line arly . the nmosfet turn s of f when the inductor current re a che s the current comma nd level. the UP6007 modulate s on-ti me of nmosfet by cha nging the current comma nd to regulate the led current. dimming control the UP6007 receives a pwm signal at pwm pin for led brightness control. the pwm signal is flatted by a low pa ss f ilter to get a reference voltage that is proportion al to the duty cycle of the pwm signal. the pwm frequency ra nge from 100hz to 100khz is a cce pta ble a nd yield line ar brightness control. current limit function the UP6007 features cycle-by-cycle current to prevent the device from da mage due to over current that might be re sult from abnormal operation. the UP6007 turns off the nmosfet when its current exceeds the current limit of 2.2a typical, preventing the indcutor current from continuously ra mping up. the nmosfet is turned on at next switching cycle. this minimizes the power dissipation a nd components stre sse s under over loa d a nd short-circuits conditions. over v oltage prote ction the over voltage prote ction prevents da mage to UP6007 during high output voltage conditions. when the output voltage is higher tha n thre shold li mit, the converter stops switching a nd the output voltage de cays. switching would be turned on again when the voltage of the ovp pin drops below the below the lower hysteresis limit. over t e mperature prote ction the excessive internal dissipation of thermal protection will malfunction UP6007. the junction over-temperature threshold is 160 o c with 30 o c of temperature hysteresis. the output voltage resumes when the over temperature fault condition is removed. upi confidential
