www.austriamicrosystems.com revision 1.03 7 - 17 as1322 austria micro systems data sheet 8 detailed description the as1322/as1322b can operate from a single-cell input voltage (v in ) below 1v, and feature fixed frequency (1.2mhz) and current mode pwm control for exceptional line- and load-regulation. with low r ds(on) and gate charge internal nmos and pmos switches, the devices main tain high-efficiency from light to heavy loads. modern portable devices frequently spend extended time in low-power or standby modes, switching to high power- drain only when certain functions are enabled. the as1322a and the as1322b are ideal for portable devices since they maintain high-power conversion efficiency over a wide output power range, thus increas ing battery life in these types of devices. in addition to high-efficiency at moderate and heavy l oads, the as1322a includes an automatic powersave mode that improves efficiency of the power converte r at light loads. the powersave mode is initiated if the output load current falls below a factory programmed threshold (see figure 3 on page 5) . note: the as1322b does not support powersave mode and provides continuous oper ation at light loads, eliminating low-frequency v out ripple at the expense of light load efficiency. figure 15. block diagram low-voltage start-up the as1322 requires v in of only 0.85v (typ) or higher to start up. the lo w-voltage start-up circuitry controls the internal nmos switch up to a maximum peak inductor current of 850ma (typ), with 1.5ms (approx. ) off-time during start-up, allowing the devices to start up into an output load. with a v out > 2.3v, the start-up circuitry is disabled and normal fixed-frequency pwm operation is initiated. in this mode, the as1322 operates independent of v in , allowing extended operating time as the battery can drop to several tenths of a volt without affect ing output regulation. the limiting factor for the application is the ability of the battery to supply sufficient energy to the output. as1322 + ? start up osc pwm control a/b mux slope compensator 1.2mhz ramp generator + ? powersave operation control ? shutdown control pwm comp + ? 1.23v ref sync drive control a b v out good 2.3v g m error amp shutdown powersave 0.35 ? 0.45 ? r 2 640k ? 1% r 1 1.02m ? 1% c ff * c out 4.7f 3.3v output l1 4.7h c in 1f 1.5v single cell * optional current sense r c 80k ? c p2 2.5pf c c 150pf gnd 2 sw 1 4 shdnn 3 fb 6 v in 5 v out
www.austriamicrosystems.com revision 1.03 8 - 17 as1322 austria micro systems data sheet low-noise fixed-frequency operation oscillator the as1322 switching frequency is internally fixed at 1.2m hz allowing the use of very small external components. error amplifier the integrated error amplifier is an internally compensated trans-conductance (g m ) type (current output). the internal 1.23v reference voltage is compared to the voltage at pin fb to generate an error signal at the output of the error amplifier. a voltage divider from v out to gnd programs the output voltage from 2.5 to 5v via pin fb as: v out = 1.23v(1 + (r 1 /r 2 )) (eq 1) current sensing a signal representing the internal nmos-switch current is summed with the slope compensator. the summed signal is compared to the error amplifier output to provide a peak cu rrent control command for the pwm. peak switch current is limited to approximately 850ma independent of v in or v out . zero current comparator the zero current comparator monitors the inductor current to the output and shuts off the pmos synchronous rectifier once this current drops to 20ma (approx.). this prevents t he inductor current from reversing polarity and results in improved converter efficiency at light loads. anti-ringing control anti-ringing control circuitry prevents high-frequency ringing on pin sw as the inductor current approaches zero. this is accomplished by damping the resonant circuit form ed by the inductor and the capacitance on pin sw (c sw ). powersave oper ation (as1322a) in light load conditions, the integrated powersave feature removes power from all circuitry not required to monitor v out . when v out has dropped approximately 1% from nominal, the as1322a powers up and begins normal pwm operation. c out (see figure 15 on page 7) recharges, causing the as1322a to re-ent er powersave mode as long as the output load remains below the powersave threshold. the frequency of this intermittent pwm is proportional to load current; i.e., as the load current drops further below the powersave threshold, the as1322a turns on less frequently. when the load current increases above the power save threshold, the as1322a will resume continuous, seamless pwm opera- tion. notes: 1. an optional capacitor (c ff ) between pins v out and fb in some applications can reduce v outp-p ripple and input quiescent current during powersave mode. typical values for c ff range from 15 to 220pf. 2. in powersave mode the as1322a draws only 30a from the output capacitor(s), greatly improving converter effi- ciency.
