upi confidential up6014 4 up6014-ds-p0000, july 2015 www.upi-semi.com functional description the up6014 integrates an n-channel and p-channel mosfets to realize a synchronous rectifier. 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 bat v bat supplies current to internal control circuits and output voltages. the supply voltage range is from 2.5v to 5.5v. a power on reset (por) continuously monitors the input supply voltage. the por level is typically 2.2v at v bat 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 turning off to limit inductor current cycle-by-cycle. the current limit threshold will be setting to 3a when v bat > v out -0.5v. if output voltage is drop under 73% (typ) of setting, the short circuit protect function (scp) will be active. output voltage setting and feedback network the output voltage can be set from vfb to vout by a voltage divider as: ? ? ? ? ? ? + = 2r 1r 1 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 r1 for better transient response. over voltage protection when output voltage reached 6v (typ), the output over voltage will be triggered to prevent external component from being damaged. over temperature protection (otp) the otp is triggered and shuts down the up6014 if the junction temperature is higher than 160 o c. the otp is a non-latch type protection. the up6014 automatically initiates another soft start cycle if the junction temperature drops below 140 o c. fixed mode the up6014 is implemented with a fixed 5.2v 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 up6014 will automatically activate its internal feedback network and regulate its output at 5.2v(typ.).
