TS3310/12/14 Data Sheet True 150 nA IQ, Selectable 1.8 to 5 VOUT Instant-On Boost Converter The TS3310/12/14 is a low power boost switching regulator with an industry leading low quiescent current of 150 nA(typ). The 150 nA is the actual current consumed from the battery while the output is in regulation. The TS3310’s extremely low power internal circuitry consumes 120 nA on average, with periodic switching cycles which service the load occurring at intervals of up to 25 seconds, together yielding the average 150 nA. The TS3310/12/14 steps up input voltages from 0.9 V (TS3312: 2 V) to 5 V to sixteen selectable output voltages ranging from 1.8 V to 5 V. The TS3310/12/14 includes two output options, one being an always-on storage output while the additional output is an output load switch that is designed to supply burst-on loads in a low duty cycle manner. The TS3310/12/14 operates in Discontinuous Conduction Mode with an on-time proportional to 1/VIN, thereby limiting the maximum input current by the selection of the inductor value, ensuring the input current does not drag down the input source. The extremely low quiescent current combined with the output load switch make the TS3310/12/14 an ideal choice for applications where the load can be periodically powered from the output, while being disconnected from the output storage capacitor when the load is powered off to isolate the load’s leakage current. The TS3310/12/14 is fully specified over the –40 °C to +85 °C temperature range and is available in a low-profile, thermally-enhanced 10-pin 2x2 mm TDFN package with an exposed back-side paddle.

Rev. 1.0 | 2 TS3310/12/14 Data Sheet System Overview 2.2.1 Theory of Operation The TS3310/12/14 is a boost switching regulator with an industry leading low quiescent current of 150 nA.The 150 nA is the actual current consumed from the battery while the output is in regulation. The TS3310/12/14’s extremely low power internal circuitry consumes 120 nA on average, with periodic switching cycles which service the load occurring at intervals of up to 25 seconds, as displayed in the scope captures titled “Input Quiescent Current : Circuit A with No-Load” in 3.1 Typical Performance Characteristics. The alwayson output voltage at STORE is regulated by a comparator within the Regulation Control block. When a load discharges CSTORE and causes the output voltage to drop below the desired regulated voltage, switching periods are initiated. When the output voltage is at or above the desired regulated voltage, the comparator causes switching periods to stop. Each switching cycle includes an ON period and an OFF period. During the ON period, the NMOS switch turns on to ramp current in the inductor, while during the OFF period, the NMOS switch turns off and the PMOS switch turns on to discharge inductor current into the CSTORE capacitor. When the ON and OFF cycles have completed, the PMOS switch turns off. The TS3310/12/14 operates in Discontinuous Conduction Mode (DCM); during any given switching cycle, the inductor current starts at and returns to zero. The switching cycle timing is governed by the Control block, which determines the ON and OFF periods according to the input and output voltages, regardless of the inductor current. The Control block sets the ON period according to the following equation: tON = 2.2 µs V IN Equation 1. ON Period Calculation Then, the choice of inductor value determines the peak switching currents: I pk = V IN × tON 2.2 µs = L L Equation 2. Peak Current Calculation The average input current, IIN(AVG), will vary according to the load, since as the load is increased, the time between switching cycles is decreased. However, IIN(AVG) will never exceed IIN(AVG,MAX), the maximum averaged input current, which represents the case where switching periods are continuously initiated. I IN (AVG,MAX ) = I pk 2 = 1.1 µs L Equation 3. Maximum Average Input Current Calculation The above equation shows that an input current limit can be set by choice of inductor value, set appropriately for the capacity and output impedance of the input source. Maximum available output current is also a function of inductor value for the case where switching cycles are continuously initiated, the expected maximum STORE output current is: I STORE (MAX ) = V IN V OUT × I IN (AVG,MAX ) × Efficiency Equation 4.

Rev. 1.0 | 4 TS3310/12/14 Data Sheet System Overview 2.2.3 Output Load at Startup, VGOOD Output, and UVLO Feature The TS3310/12/14 provides an Open-Drain VGOOD output that assumes a high impedance once the STORE output is greater than 90% of the target voltage. At startup, the TS3310/12/14 can provide 5% of the maximum STORE output load current. Once the Open-Drain VGOOD output has assumed a high impedance, the TS3310/12/14 can be loaded with the expected maximum STORE current. The startup time varies depending upon the input voltage, output voltage selection, inductor, and input/output capacitor configuration. The TS3310 and TS3314 come with an Under Voltage Lockout (UVLO) feature at 0.9 V, while the TS3312 comes with a UVLO feature at 2 V. TS3310 and TS3314 UVLO features have a 20 mV hysteresis. The TS3312 UVLO feature has a 100 mV hysteresis. The UVLO feature monitors the input voltage and inhibits the Switching Cycle Controls from initiating switching cycles if the VIN is too low. This ensures no switching currents are drawn from the input to collapse the voltage at the terminals of the battery when the internal resistance of the battery is high. The following figure displays the UVLO feature for the TS3310. Figure 2.2. TS3310, UVLO = 0.9 V silabs.com | Smart. Connected. Energy-friendly. Rev. 1.0 | 5 TS3310/12/14 Data Sheet System Overview 2.2.4 Inductor Selection When selecting an inductor value, the value should be chosen based on output current requirements. If the input source is a small battery, make sure the choice of the inductor value considers the maximum input current that the source battery can support (based on series resistance). For example, some small button cell batteries can exhibit 5Ω series resistance, therefore a 20 mA maximum input current may be appropriate (100 mV drop). Consider using a large STORE capacitor to support peak loads for small batteries (see 2.2.6 Bursted Load with Big STORE Buffer Capacitor). Figure 2.3. Expected Maximum STORE Output Current with 85% Efficiency vs. Inductor Value Figure 2.4. IIN(AVG,MAX) vs. Inductor Value A low ESR, shielded inductor is recommended. Depending upon the application, the inductor value will vary. For applications with load currents less than a few milliamperes, a 100 μH inductor is recommended. As shown by the efficiency curves in 3.1 Typical Performance Characteristics, the efficiency is greater with a larger inductor value for smaller load currents. Please refer to the two "Maximum STORE Output Current vs. Input Voltage" graphs found in 3.1 Typical Performance Characteristics. Circuit A, which uses a 10 μH inductor, is able to source larger load currents than that of Circuit B with a 100 μH inductor due to the larger peak currents. silabs.com | Smart. Connected. Energy-friendly. Rev. 1.0 | 6 TS3310/12/14 Data Sheet System Overview Figure 2.5. Inductor Peak Current vs. Inductor Value The chosen inductor’s saturation current for a specific inductor value should be at least 50% greater than the peak inductor current value displayed in the above figure.

The tables include the inductors’ Rdc (inductor series dc resistance or ESR) saturation current and dimensions. As mentioned previously, the inductor’s saturation current should always be greater than 150% of the peak inductor current; therefore, the appropriate size and efficiency (dependent upon ESR) may be chosen based on application requirements.

Connected. Energy-friendly. Rev. 1.0 | 8 TS3310/12/14 Data Sheet System Overview 2.2.5 Input and STORE Capacitor Selection Ceramic capacitors are recommended for CIN and CSTORE, due to ceramics’ extremely low leakage currents (generally limited by very high insulation resistance). Larger value ceramics (10 μF or greater) may use high constant dielectric materials, such as X5R and X7R. These materials exhibit a strong voltage coefficient and substantially lower capacitance than rated when operated near the maximum specified voltage. For these types of capacitors, use a 10 V or greater voltage rating. The STORE voltage output ripple can be reduced by increasing the value of CSTORE. The figure below displays the STORE output voltage ripple for two different storage capacitor values. The output voltage ripple reaches a floor value when the internal voltage comparator hysteresis becomes the dominant source of ripple. Below this level, larger capacitance does not help reduce the ripple. Figure 2.6. Output Voltage Ripple Comparison silabs.com | Smart. Connected. Energy-friendly. Rev. 1.0 | 9 TS3310/12/14 Data Sheet System Overview 2.2.6 Bursted Load with Big STORE Buffer Capacitor The TS3310 provides a switched OUT output that is capable of sourcing short bursts of large output current by utilizing a large storage capacitor at the STORE output. The figure below displays an application circuit that utilizes this functionality. The circuit is powered from a LR44 1.5 V Coin Cell Battery. In this example, the load needs to be powered on once every 20 seconds for 200 μs periods. The load requires a 3.3 V source and demands 100 mA current when it is powered on. Also in this example, the load continues to consume 10 μA of leakage current when off. By attaching the load to OUT when the load isn’t used, the TS3310 isolates the 10 μA current so that overall quiescent current can be maintained. A 220 μF storage capacitor is used for CSTORE so that it can store the necessary charge to supply the 100 mA load current. The microcontroller brings the Instant-On Load Switch, OUT_ON, high when the load needs to be powered on. The TS3310 on average consumes 160 nA between load bursts. Figure 2.7. Bursted Load Application Circuit To prevent the circuit from overloading the LR44 Coin Cell Battery, a 100 μH inductor is used to ensure the TS3310 only draws 10 mA of current on average while recharging CSTORE after the load is powered off. After the load has been powered off, the TS3310 recharges the 220 μF CSTORE capacitor within 6 ms and is ready for the next bursted cycle. The following figure displays the load being powered on for a 200 μs period and the recharge of the 220 μF CSTORE within 6 ms. Figure 2.8. 220 µF CSTORE Recovery Scope Capture silabs.com | Smart.
