up6013 conceptual 4 up6013-ds-c3200, jun. 2016 www.upi-semi.com functional description the up6013 integrates an n-channel and p-channel mosfets to realize a synchronous rectifier with a current source of p-mosfets for output current regulation. the power conversion efficiency is up to 90%. since a typical step-up converter has a conduction path from the input to the output via the body diode of the p-channel mosfet, a specific circuit is used to reverse the polarity of the p- channel body diode when the part is shutdown. it certainly protects battery from being completely depleted during shutdown. input supply voltage, v in v in supplies current to internal control circuits and output voltages. the supply voltage range is from 2.7v to 5v. a power-on reset (por) continuously monitors the input supply voltage. the por level is typically 2.5v at v in rising. a minimum 47uf ceramic capacitor with shortest pcb traces is highly recommended for bypassing the supply input. current limit function when the inductor current is higher than current limit threshold, the current limit function activates and forces the n-channel mosfet to turn off the limit inductor current cycle-by-cycle. if output voltage drops under 73% (typ) of setting, the short circuit protection (scp) will be activated and latch off the output of boost converter. to restart the output after latch-off, please input enable signal again. output voltage setting and feedback network the output voltage can be set from vfb to vout by a voltage divider as: ? ? ? ? ? ? + = 4 3 1 r r v v fb out the internal vref is 1.227v with 1.5% accuracy. in real applications, a 22pf feedforward ceramic capacitor is recommended in parallel with r3 for better transient responses. output current control the up6013 is built-in with a current source of p-mosfets for output current control. the p-mosfets can be turned on or turned off to regulate output current through a pwm input (pwm_ctl) or dc input (dc_ctl). it supports external pwm input frequency from 1khz to 100khz, the relationship between pwm_ctl with cs duty can be shown as figure 1. when using dc input control, the output current duty corresponds to dc_ctl is 0.25~1.15v and the dc control input voltage can be achieved by setting the ratio of r1 and r2 resistors. ? ? ? ? ? ? + = 2 1 2 2.1 _ r r r v ctl dc then the dc control input voltage corresponds to output current duty can be shown as: du ty current output v v min ctl dc max ctl dc = 9.0 _ _ where input range of v dc_ctl = 0.25v ~ 1.15 v keep v dc_ctl between 0.25v and 1.15v, if v dc_ctl falls under 0.25v, the current source output will keep in minimum on duty. 0 20 40 60 80 100 0 102030405060708090100 pwm_ctl = 1khz pwm_ctl = 100khz fixed modethe up6013 is implemented with a fixed 5v output voltage function without the need of an external feedback voltage divider. if the fb pin is shorted to gnd during device start- up, the up6013 will automatically activate its internal feedback network and regulate its output at 5v. over temperature protection (otp) the otp is triggered and shuts down the up6013 if the junction temperature reaches higher than 160 o c. the otp is a non-latch type of protection. the up6013 automatically initiates another soft start cycle if the junction temperature drops below 140 o c. thermal fold back the thermal fold back function can monitor ic temperature to keep heating wires continuously working. when the junction temperature exceeds 120 o c, the up6013 will switch into thermal fold back mode and current source duty cycle will be set to 50% of normal operation to decrease output current. the up6013 will return to normal operation once the junction temperature drops down to 80 o c. figure 1. pwm_duty vs. cs duty pwm_ctl duty (%) current source duty (%) upi confidential
