AS1313 Ultra Low Quiescent Current, DC-DC Step Down Converter General Description The AS1313 is an ultra-low quiescent current hysteretic step-down DC-DC converter optimized for light loads and with efficiencies of up to 95%. AS1313 operates from a 2.4V to 5.5V supply and supports output voltages between 1.2V and 3.6V. Besides the available AS1313 standard variants, any variant with output voltages in 50mV steps are available. In order to save power the AS1313 features a shutdown mode, where it draws less than 100nA. During shutdown mode the battery is disconnected from the output. In light load operation, the device enters an idle mode when most of the internal operating blocks are turned off in order to save power. This mode is active approximately 100μs after a current pulse provided that the output is in regulation. The capacitor connected to the REF pin is an essential part of this feature. The AS1313 is available in an 8-pin MLPD (2mm x 2mm) and a 6-pin WL-CSP (0.4mm pitch). Ordering Information and Content Guide appear at end of datasheet.

This means the triggering of the on-off switching of the internal switches depends only on comparators measuring the output voltage and the coil current measurement. This lead to a very low quiescent current. In addition, because there is no fixed timing reference, the operating frequency is determined by external components (inductor and capacitors) and the loading on the output. Detailed Description Ripple at the output is an essential operating behavior. A power cycle is initiated when the output regulated voltage drops below the nominal value of V OUT.

With neglecting the resistive voltage drop over SW1 the voltage across the coil is: V COIL – on = V IN – V OUT Based on the expression, which shows the correlation between voltage across the coil and the coil current, it's easy to rearrange this equation to get the coil current I COIL generated while SW1 is closed (tON).

With neglecting the resistive voltage drop over SW2 the voltage across the coil is: V COIL – off = V OUT Similar to the expression above, the I COIL generated while SW2 is closed (tOFF ) can be expressed as: (EQ2) V OUT I COIL = -------------- ⋅ t OFF L The increasing coil current during the charging (SW1 closed) and the decreasing coil current during the discharging of the coil (SW2 closed) must be the same. Hence, it’s easy to calculate the duty cycle of SW1. (EQ3) t ON V IN – V OUT V OUT V OUT I COIL = ------------------------------ ⋅ t ON = -------------- ⋅ t OFF -------------- = -------------------------- L L V IN t ON + t OFF Based on the EQ1, the on time of SW1 can be given by: (EQ4) L t ON = ------------------------------ ⋅ I COIL V IN – V OUT Figure 14: Simplified Voltage and Current Diagram V VIN VIN VCOIL A A VOUT_ripple VOUT_nom VIDLE 0 VCOIL B C D B -VOUT t I IPK 400mA ICOIL ILOAD 0 tON tOFF SW1 on SW2 off SW1 off SW2 on tWAIT tIDLE SW1 off SW2 off tON tOFF SW1 on SW2 off SW1 off SW2 on t Timing Diagram: This figure shows the relationship between the current and the voltages inside the loop within the switching cycle. Page 12 Document Feedback ams Datasheet [v1-43] 2015-Jul-23 AS1313 − Detailed Description If the V OUT falls below the V OUT_nom, SW1 closes and the coil current increases until the max. coil current of 400mA is reached. During this time tON, the V OUT increases. With reaching the 400mA, the switch SW1 opens immediately, the SW2 closes and the coil current decreases down till it reaches the zero line. After this, SW2 opens and if the V OUT is then above the V OUT_nom, no further pulse is needed, both switches remain in their open position, hence no coil current is flowing. In this phase the needed output power only comes out of the COUT. This time is called t WAIT, which takes ~100us. If the V OUT falls below V OUT_nom within the time t WAIT, the SW1 closes and the charging cycle starts again. If the V OUT is still higher than V OUT_nom after t WAIT is elapsed, then the AS1313 falls into an idle mode, which results in a reduction of the quiescent current. Once, the AS1313 is in this idle mode, the idle-comparator is comparing VOUT with V IDLE (98% of V OUT_nom) and SW1 closes as soon as the V OUT reaches this threshold. ams Datasheet [v1-43] 2015-Jul-23 Page 13 Document Feedback AS1313 − Detailed Description External Component Selection Inductors For best efficiency, choose an inductor with high frequency core material, such as ferrite, to reduce core losses. The inductor should have low DCR (DC resistance) to reduce the I²R losses, and must be able to handle the peak inductor current without saturating. A 6.8μH inductor with at least 500mA current rating and DCR of 500mΩ (max) is recommended.

Recommended ceramic X5R or X7R types will minimize ESL and ESR while maintaining capacitance at rated voltage over temperature. The input capacitor supports the triangular current during the on-time of SW1 and maintains a broadly constant input voltage during this time. The capacitance value is obtained from choosing a ripple voltage during the on-time of SW1. (EQ5) I COIL C IN = --------------------- ⋅ t ON V RIPPLE Using tON = 1μs, I COIL = 400mA and V RIPPLE = 50mV, EQ5 yields: C IN = 8μF. Because ceramic capacitors lose a lot of their initial capacitance at their maximum rated voltage, it is recommended that either a higher input capacity or a capacitance with a higher rated voltage is used. A 22μF cap for C IN is recommended. Additionally, ripple voltage is generated by the equivalent series resistance (ESR) of the capacitor. (EQ6) V RIPPLE – ESR = I COIL ⋅ R ESR The output capacitor supports the triangular current during the off-time SW1 (coil discharge period), and also the load current during the wait time (Region C) and the idle time (Region D). (EQ7) I OUT C OUT = ------------------------------------------- ⋅ ( t WAIT + t IDLE ) 0.02 ⋅ V OUT – nom Using tWAIT = 100μs, tIDLE = 500μs, I OUT = 1mA and V OUT_nom = 3.3V, EQ7 yields: COUT = 9μF. Due to the DC bias of the cap and to sustain also load steps, the COUT should be between 22μF and 47μF. A larger output capacitor should be used if lower peak to peak output voltage ripple is desired. A larger output capacitor will also improve load regulation on V OUT. ams Datasheet [v1-43] 2015-Jul-23 Page 15 Document Feedback AS1313 − Detailed Description Figure 16: Recommended Input & Output Capacitors C TC Code Voltage Rating Size in mm (L/W/H) GRM21BR60J226ME39L 22μF X5R 6.3V 2x1.25x1.25 GRM31CR61A226ME19L 22μF X5R 10V 3.2x1.6x1.6 12066D226KAT_A 22μF X5R 6.3V 3.2x1.6x1.78 1210ZD226KAT_A 22μF X5R 10V 3.2x1.6x1.78 1210YD226KAT_A 22μF X5R 16V 3.2x1.6x1.78 C2012X5R0J226K/1.25 22μF X5R 6.3V 2x1.2x1.25 C2012X5R1A226K/1.25 22μF X5R 10V 2x1.2x1.25 C2012X5R1C226K 22μF X5R 16V 2x1.2x1.25 Part Number Manufacturer Murata www.murata.com AVX www.avx.com TDK www.tdk.com For C REF a 100nF cap (X5R or better) is recommended.
