With a minimum of +1.5V input voltage, the device is well suited for applications with one- or two-cells, such as lithium ion (Li+), nickel-metal-hydride (NiMH), or alkaline. Figure 26. Block Diagram +5.0V Output only +1.5 to +3.3V or +1.5 to +5.0V Battery CIN 22µF Zero Crossing Detector 4 10µH LX 5 OUT COUT 22µF +3.3 or +5.0V Output Startup Circuitry AntiRinging Switch Driver and Control Logic – + 2 +1.228V BATT VREF Current Limiter – 1 AS1325 SHDNN GND +1.1V + 6 RESETN 3 The input battery is connected to the device through an inductor and an internal P-FET when pin SHDNN is low. In this state, the step-up converter is off and the voltage drop across the P-FET body diode is eliminated, and the input battery can be used as a battery-backup or real-time-clock supply. The built-in synchronous rectifier significantly improves efficiency. Control Circuitry The AS1325 integrated current-limited key circuitry provides low quiescent current and extremely-high efficiency over a wide VOUT range without the need for an oscillator. Light Loads: Inductor current is limited by the 0.4A N-channel current limit or by the 7µs switch maximum on-time. The lower current limit reduces the ripple of the output voltage. At each cycle, the inductor current must ramp down to zero before the next cycle may start. When the error comparator senses that the output has fallen below the regulation threshold, another cycle begins. Higher Loads: If after the first light load cycle the output voltage has not reached its target value of 3.3V or 5.0V, the inductor current limit is increased to 0.7A. After the P-channel minimum on-time the next loading cycle is started if the output voltage is still below its target value. If the target value is reached, the inductor current must ramp down to zero before the next cycle may start. When the error comparator senses that the output has fallen below the regulation threshold, another load cycle begins (see Figure 12 on page 6 and Figure 24 on page 8). www.austriamicrosystems.com Revision 1.00 9 - 16 austriam i c r o systems AS132 5 Data Sheet Shutdown Shutdown When pin SHDNN is low the AS1325 is switched off and no current is drawn from battery; when pin SHDNN is high the device is switched on. If SHDNN is driven from a logic-level output, the logic high-level (on) should be referenced to VOUT to avoid intermittently switching the device on. Note: If pin SHDNN is not used, it should be connected directly to pin OUT. In shutdown the battery input is connected to the output through the inductor and the internal synchronous rectifier PFET. This allows the input battery to provide backup power for devices such as an idle microcontroller, memory, or realtime-clock, without the usual diode forward drop. In this way a separate backup battery is not needed. In cases where there is residual voltage during shutdown, some small amount of energy will be transferred from pin OUT to pin BATT immediately after shutdown, resulting in a momentary spike of the voltage at pin BATT. The ratio of CIN and COUT partly determine the size and duration of this spike, as does the current-sink ability of the input device. Low-Battery Cutoff The AS1325 SHDNN trip threshold (1.228V) can be used as an input voltage detector that disables the device when the battery input voltage falls to a pre-set level. An external resistor-divider network can be used to set the batterydetection voltage (see Figure 27). Figure 27. Low-Battery Cutoff Application Diagram +5.0V Output only +1.5 to +3.3V or +1.5 to +5.0V Battery 2 +3.3V or +5.0V Output 5 BATT OUT CIN 22µF R3 100kΩ 4 R1 220kΩ L1 10µH LX AS1325 RESETN 1 R2 1MΩ 10nF 6 COUT 22µF Power-On Reset 3 SHDNN GND For the resistor-divider network shown in Figure 27, calculate the value for R1 by: R1 = R2 x ((VOFF/VSHDNN) - 1) Where: VOFF is the battery voltage at which the AS1325 shuts down. VSHDNN = 1.228V (EQ 1) The value of R2 should be between 100kΩ and 1MΩ to minimize battery drain. Note: Input ripple can cause false shutdowns, therefore to minimize the effect of ripple, a low-value capacitor from SHDNN to GND should be used to filter out input noise. The value of the capacitor should be such that the R/C time constant is > 2ms. www.austriamicrosystems.com Revision 1.00 10 - 16 austriam i c r o systems AS132 5 Data Sheet Power-On Reset The AS1325 provides a power-on reset output (RESETN) that goes high-impedance when the output reaches 90% of its regulation point. RESETN goes low when the output is below 90% of the regulation point. A 100kΩ to 1MΩ pullup resistor between pin RESETN and pin OUT can provide a microprocessor logic control signal. Note: Connect pin RESETN to GND when the power-on reset feature is not used. Antiringing Control If the inductor current falls to zero, an internal 100Ω (typ) antiringing switch is connected from LX to BATT to minimize EMI. The antiringing control can be deactivated by not connecting the pin BATT. The device is supplied by the pin OUT - no supply current flows into pin BATT. www.austriamicrosystems.com Revision 1.00 11 - 16 austriam i c r o systems AS132 5 Data Sheet 8 Application Information Inductor Selection The control circuitry of the AS1325 permits a wide range of inductor values to be selected – from 4.7 to 22µH; The system is optimized for 10µH. The intended application should dictate the value of L. The trade-off between required PCB surface area and desired output ripple are the determining factors: smaller values for L require less PCB space, larger values of L reduce output ripple. If the value of L is large enough to prevent IMAX from being reached before tON expires, the AS1325 output power will be reduced. Note: Coils should be able to handle 500mARMS and have a ISAT ≥ 1A and should have a RIND ≤ 100mΩ. Capacitor Selection Low ESR capacitors (X5R or X7R) should be used to minimize the output voltage ripple. COUT Selection Choose a COUT value to achieve the desired output ripple. A 22µF ceramic capacitor is a good initial value. A larger value for COUT can be used to further reduce ripple and improve AS1325 efficiency. CIN Selection CIN reduces the peak current drawn from the battery and can be the same value as COUT. External Diode (5V Output only) An external Schottky diode must be connected, in parallel with the on-chip synchronous rectifier, from LX to OUT. Use diodes such as MBR0520L, EP05Q03L, or the generic 1N5817. The diode should be rated for 500mA, since it carries current during startup and after the synchronous rectifier turns off. The Schottky diode must be connected as close to the IC as possible. Ordinary rectifier diodes must not be used, since the slow recovery rate will compromise efficiency. PC Board Layout and Grounding Well-designed printed circuit-board layout is important for minimizing ground bounce and noise. ! Place pin GND lead and the ground leads of CIN and COUT as close to the device as possible. ! Keep the lead to pin LX as short as possible. ! To maximize output power and efficiency and minimize output ripple voltage, use a ground plane and solder the GND pin directly to the ground plane. www.austriamicrosystems.com Revision 1.00 12 - 16 austriam i c r o systems AS132 5 Data Sheet Pin Assignments 9 Pinout and Packaging Pin Assignments Figure 28.
