The S-8821 series is a CMOS boost charge pump DC-DC converter with a voltage regulation function.
The S-8821 series consists of an oscillation circuit, a controller, a reference voltage circuit, an error amplifier
circuit, and an output switching transistor, and can regulate the output voltage by PFM control.
Since small ceramic capacitors can be used for the pump capacitor, input capacitor, and output capacitor, the
mounting area can be minimized.

Operation
1. Basic operation
Figure 7 shows the block diagram of the S-8821 Series.
The S-8821 series controls the output voltage by using the pulse frequency modulation (PFM) method.
The SW1 to SW4 switching transistors are switched ON/OFF with the clock generated by the internal
oscillator circuit, and operates the boost charge pump.
The output voltage is fed back and the voltage split by feedback resistances Rs and Rf and reference
voltage (Vref) are compared by a comparator. This comparator signal is used to modulate the oscillation
pulse frequency in order to keep the output voltage constant.

2. Boost Charge Pump
The boost charge pump boosts the voltage by switching ON/OFF of the SW1 to SW4 switching
transistors.
First, in order to charge the pump capacitance (CPUMP), set SW1 to OFF, SW2 to ON, SW3 to OFF, and
SW4 to ON (charge cycle). Following charging the electricity, in order to discharge the charged
electricity to the output capacitance (COUT), SW1 set the switches as to ON, SW2 to OFF, SW3 to ON,
and SW4 to OFF (discharge cycle).
The input voltage can be boosted to a constant voltage value by repeating this charge cycle and
discharge cycle.
Figure 8 shows the charge cycle, and Figure 9 shows the discharge cycle.

3. Shutdown Pin (ON/OFF Pin)
Setting the ON/OFF pin to the Low level ("L") causes the voltage of the VOUT pin to change to the GND
level and simultaneously the operation of all the internal circuit to stop. At this time, the consumption
current is largely reduced, to a level of approximately 0.3 μA.
The structure of the ON/OFF pin is as shown in Figure 10. Since the ON/OFF pin is neither pulled
down nor pulled up internally, do not use it in the floating state.
When the ON/OFF pin is not used, connect it to the VIN pin.

4. Soft Start Function
The S-8821 Series features a built-in soft start circuit. Upon power application or when the ON/OFF pin
is switched from "L" to "H", the output voltage gradually rises over the soft start time, and the output
current is gradually output as a result. This soft start function reduces the input current rush.

External Capacitor Selection
1. Input and Output Capacitors (CIN, COUT)
The input capacitor (CIN) lowers the power supply impedance and averages the input current.
The CIN value is selected according to the impedance of the power supply that is used. Select a ceramic
capacitor with a small equivalent series resistance (ESR). Although this figure varies according to the
impedance of the power supply that is used as well as the load current value, it is generally in the range
of 4.7 μF to 10 μF.
For the output capacitor (COUT), select a ceramic capacitor with a small ESR for smoothing the ripple
voltage. A value of 10 μF is recommended for the capacitance value. Use of a capacitor with a
capacitance lower than 10 μF results in a larger ripple voltage. Conversely, use of a capacitor with a
capacitance greater than 10 μF results in the output voltage not being able to rise up to setting value
and the impossibility to obtain the desired output current.
2. Pump Capacitor (CPUMP)
The pump capacitor (CPUMP) is required for boosting the voltage. Select a ceramic capacitor with a small
ESR. A capacitance value of 0.10 μF is recommended. Use of a capacitor with a capacitance greater
than 0.10 μF results in a larger ripple voltage. Conversely, use of a capacitor with a capacitance lower
than 0.10 μF results in the output voltage not being able to raise up to setting value and the impossibility
to obtain the desired output current.

Precautions
• Regarding the wiring to the VIN pin, VOUT pin, C+ pin, C− pin and GND pin, be careful to perform
pattern wiring so as to obtain low impedance.
• Always connect a capacitor to the VOUT pin, C+ pin, and C− pin.
• Connect CIN and COUT in the vicinity of the IC and sufficiently strengthen the wiring for GND pin and VIN
pin in order to lower the impedance of the wiring resistance, etc. High impedance may cause unstable
operation.
Moreover, in selecting CIN and COUT, perform a full evaluation of the actual usage conditions.
• Connect CPUMP in the vicinity of the IC and sufficiently strengthen the wiring for the C+ pin and C− pin in
order to lower the impedance of the wiring resistance, etc. High impedance may cause instable
operation.
Moreover, in selecting CPUMP, perform a full evaluation of the actual usage conditions.
• The ON/OFF pin is configured as shown in Figure 9 and is neither pulled up or down internally, so do not
use this pin in a floating state. When not using the ON/OFF pin, connect it to the VIN pin.
Moreover, please do not apply voltage higher than VIN + 0.3 V to an ON/OFF pin. Current flows for a
VIN pin through the protection diode inside IC.
• Since this IC consists of double boost circuits, it cannot set more than twice voltage of VIN to VOUT(S).
• Be careful about the usage conditions for the input/output voltages and output current to make sure that
dissipation within the IC does not exceed the allowable power dissipation of the package.
For reference, the calculation of the power consumption in this IC is shown below.
PD=(VIN × 2.0 − VOUT) × (IOUT)
Reference: VIN=4.2 V, VOUT=5.5 V, IOUT=10 mA
PD=(4.2 × 2.0 − 5.5) × 0.010=29 mW
• Since the information described herein is subject to change without notice, confirm that this is the latest
one before using.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in
electrostatic protection circuit.
• ABLIC Inc. claims no responsibility for any and all disputes arising out of or in connection with any
infringement of the products including this IC upon patents owned by a third party.
