1/26 xc6222 series 700ma high speed ldo regulator with reverse current protection general description the xc6222 series is a highly accurate, low noise, high ripple rejection, low dropout, and low power consumption high speed cmos voltage regulator. the series consists of a voltage refe rence, an error amplifier, a driv er transistor, a current limiter , a thermal protection circuit, a reverse current prot ection circuit and a phase compensation circuit. the ce function enables the entire circuit to be placed in a stand- by state by inputting a low level signal to the ce pin. in this stand-by mode, the electric c harge at the output capacitor (c l ) will be discharged by the internal auto-discharge switch, and as a result the v out pin will quickly return to the v ss level. over-current protection and thermal protection circuits are in tegrated. the protection circuit starts to operate when either ou tput current reaches the current limit level or junction temperat ure reaches the temperature limi t. with the reverse current protection function, the reverse current flow is prohibited when v out voltage is higher than v in voltage. the protection diode of ic is not necessary. typical application circuit etr0344-005a a pplications usb products cd/dvd/hdd drives mobile phones portable game consoles camera modules electronic dictionaries *c l 2.2 f or higher (v out =2.5 5.0v) 4.7 f or higher (v out =2.1 2.45v) 6.8 f or higher (v out =0.8 2.05v) features maximum output current dropout voltage : 700ma : 120mv @i out =300ma(v out =3.0v) operating voltage range : 1.7v ~ 6.0v output voltages : 0.8v~5.0v (0.05v increments) accuracy : + 1% (v out 2.0v) + 0.02v (v out Q 2.0v) low power consumption : 100 a (v out =3.0v) high ripple rejection : 65db @ 1khz operating temperature : -40 ~+85 low esr capacitor chip enable(ce) : ceramic capacitor : active high,c l discharge standby current below 0.1 a packages : usp-6c, sot-25, sot-89-5 environmentally friendly : eu rohs compliant, pb free ?^? xc6222x151 1.1 1.2 1.3 1.4 1.5 1.6 time100s/div output voltagev out (v) 0 200 400 600 800 1000 output currenti out (ma) tr=tf=5s,v in =2.5v, ta=25 v out =10300ma, c in =1.0f(ceramic), c l =6.8f(ceramic) output current output voltage typical performance characteristics load transient response

8/26 xc6222 series operational explanation the voltage divided by two resistors r1 and r2 is compared with the internal reference voltage by the error amplifier. the p-channel mosfet connected to the v out pin, is then driven by the subsequent out put signal. the output voltage at the v out pin is controlled and stabilized by a system of negative feedback. the current limit and short pr otection operate in relation t o the level of output current. the thermal pr otection operates in relation to the leve l of heat generation. the reverse current protection operates when v out voltage is higher than v in voltage. further, the ic's internal circuitry can be turned off via the ce pin's signal. the xc6222 needs an output capacitor c l for phase compensation. values required for the phase compensation are shown in the chart below. if a loss of the capacitance happens, stabl e phase compensation may not be obtained. please ensure to use a capacitor which does not depend on bias or temperature too much. for a stable power input, please connect an input capacitor c in of 1.0 f between the v in pin and the v ss pin. output voltage (v) output capacitor value 0.8v 2.05v c l =6.8 f (min.) 2.1v 2.45v c l =4.7 f (min.) 2.5v 5.0v c l =2.2 f (min.) the xc6222 series includes reverse current protection to prevent the damage to any connected products such as batteries as a result of current flow from the v out pin to the v in pin. when v in is smaller than v out, the reverse current protection works and suppress the reverse current to 1.5 a (max.). when v in is smaller then v out , the v out pin sink current flows from the v out pin to the v ss pin is 95 a (typ.) as the ic operation current. with the xc6222a/c series, when a low level signal is inputted to the ce pin, the sink current of the v out pin is minimized to 2.8 a (typ.). however, with the xc6222b/d series, when a low level signal is inputted to the ce pin, the sink current of the v out pin goes through the c l auto discharge circuit to the v ss pin which may result in the ic being damaged. in this case, please do not connect a power supply to the v out pin. please also note when the xc6222a/c series connects external power supply to the v out pin, please use it within the range from v out(e) (actual output voltage value)or more to 6.0v or less. when the voltage less than v out(e) is applied to the v out pin by adding a power supply or battery, a low level signal should be input to the ce pin for chip disable in order to protect a rever se current at v in < v out . example) the voltage less than v out(e) (actual output voltage value) is applied to the v out pin as "or" connection. on/off control + - error amp voltage reference each circuit currentlimit & thermalshutdown r1 r2 cfb xc6222aseries vin ce vss vout reverce current protection output capacitor (c l ) table * when the ce pin is connected to the v in pin, an output voltage 2.8v from the step-up dc/dc goes through to the v in pin as reverse current up to around 150ma if the usb connection is removed from the v in pin (v in < v out ). ce pin voltage should be maintained low when the usb connection is removed from the v in pin.
9/26 xc6222 series the xc6222 series? fold-back circuit operates as an output current limiter and a short protection circuit for the output pin. when the load current reaches the current limit level, the fixe d current limiter circuit operates and output voltage drops. whe n the output pin is short-circuited to the v ss pin, the current is decreased to a level of 55ma. when the junction temperature of the built-in driver transistor reache s the temperature limit level (150 typ.), the thermal shutdown circuit operates and the driver transistor will be turned off. the ic resumes its operation when the thermal shutdown function is released and the ic?s operation is auto matically restored because the junction temperature drops to the level of 125 (typ.) as the thermal shutdown release voltage. operational explanation (continued) xc6222b/d series can discharge the electric charge stored in the output capacitor (c l ), when a low signal to the ce pin, which enables the whole ic circuit to be turned off, is inputted via the n-channel transistor located between the v out pin and the v ss pin (cf. block diagram). the cl auto-discharge resistance value is set at 530 (typ.). the discharge time of the output capacitor (c l ) is set by the cl auto-discharge resistance (r) and the output capacitor (c l ). by setting the time constant of the c l auto-discharge resistance value [r dchg ] and the output capacitor value (c l ) as ( =c x r dchg ), the output voltage after discharge via the n-channel transistor is calculated by the following formula. v = v out(e) x e ?t/ , or t= in ( v / v out(e) ) where v: output voltage after discharge v out (e) : output voltage t: discharge time : c l auto-discharge resistance r dchg output capacitor (c l ) value c) the entire xc6222 circuitry can be turned off via the ce pin signal. in shutdown mode, output at the v out pin will be pulled down to the v ss level via r1 & r2. however, with the xc6222b series, the c l auto-discharge resistor is connected in parallel to r1 and r2 while the power supply is applied to the v in pin. therefore, time until the v out pin reaches the v ss level is shorter. for the xc6222a/b series, the output voltage bec omes unstable, when the ce pin is left open. if this ce pin voltage is set wit h the specified voltage range, t he logic is fixed and the ic will operate normally. however, the supply current may increase as a result of shoot-through current in the ic's internal circuitry w hen a medium voltage is input to the ce pin. with the xc6222c/ d series, when the ce pin is left open, output voltage is fixed to v ss level. notes on use 1 . please use this ic within the stated absolute maximum rati ngs. the ic is liable to malfunction should the ratings be exceeded. 2. where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. please wire the input capacitor (c in ) and the output capacitor (c l ) as close to the ic as possible.
