S-8353/8354 Series
STEP-UP, PWM CONTROL or PWM / PFM SWITCHABLE
BUILT-IN TRANSISTOR SWITCHING REGULATOR
www.sii-ic.com
© SII Semiconductor Corporation, 2002-2010
Rev.3.0_01
The S-8353/8354 Series is a CMOS step-up switching regulator which mainly consists of a reference voltage source, an
oscillation circuit, a power MOS FET, an error amplifier, a phase compensation circuit, a PWM control circuit (S-8353 Series)
and a PWM / PFM switching control circuit (S-8354 Series).
The S-8353/8354 Series can configure the step-up switching regulator with an external coil, capacitor, and diode. In
addition to the above features, the small package and low current consumption make the S-8353/8354 Series ideal for
portable equipment applications requiring high efficiency.
The S-8353 Series realizes low ripple, high efficiency, and excellent transient characteristics due to its PWM control circuit
whose duty ratio can be varied linearly from 0% to 83% (from 0% to 78% for 250 kHz models), an excellently designed error
amplifier, and phase compensation circuits.
The S-8354 Series features a PWM / PFM switching controller that can switch the operation to a PFM controller with a duty
ratio is 15% under a light load to prevent a decline in the efficiency due to the IC operating current.
Features
• Low voltage operation: Startup at 0.9 V min. (IOUT = 1 mA) guaranteed
• Low current consumption : During operation 18.7 μA (3.3 V, 50 kHz, typ.)
During shutdown: 0.5 μA (max.)
• Duty ratio : Built-in PWM / PFM switching control circuit (S-8354 Series)
15 % to 83 % (30 kHz and 50 kHz models)
15 % to 78 % (250 kHz models)
• External parts : Coil, capacitor, and diode
• Output voltage : Selectable in 0.1 V steps between 1.5 V and 6.5 V (for VDD / VOUT separate types)
Selectable in 0.1 V steps between 2.0 V and 6.5 V (for other than VDD / VOUT separate types)
• Output voltage accuracy : 2.4%
• Oscillation frequency : 30 kHz, 50 kHz, and 250 kHz selectable
• Soft start function : 6 ms (50 kHz, typ.)
• Lead-free, Sn 100%, halogen-free*1
*1. Refer to “ Product Name Structure” for details.

Operation
1. Switching Control Types
1. 1 PWM Control (S-8353 Series)
The S-8353 Series is a DC-DC converter using a pulse width modulation method (PWM) and features low current
consumption. In conventional PFM DC-DC converters, pulses are skipped when the output load current is low,
causing a fluctuation in the ripple frequency of the output voltage, resulting in an increase in the ripple voltage.
In the S-8353 Series, the switching frequency does not change, although the pulse width changes from 0% to
83% (78% for H and J type) corresponding to each load current. The ripple voltage generated from switching can
thus be removed easily using a filter because the switching frequency is constant.
1. 2 PWM / PFM Switching Control (S-8354 Series)
The S-8354 Series is a DC-DC converter that automatically switches between a pulse width modulation method
(PWM) and a pulse frequency modulation method (PFM), depending on the load current, and features low current
consumption.
The S-8354 Series operates under PWM control with the pulse width duty changing from 15% to 83% (78% for H
and J type) in a high output load current area. On the other hand, the S-8354 Series operates under PFM control
with the pulse width duty fixed at 15% in a low output load current area, and pulses are skipped according to the
load current. The oscillation circuit thus oscillates intermittently so that the resultant lower self current
consumption can prevent a reduction in the efficiency at a low load current. The switching point from PWM
control to PFM control depends on the external devices (coil, diode, etc.), input voltage, and output voltage. This
series are an especially efficient DC-DC converter at an output current around 100 μA.
2. Soft Start Function
For this IC, a built-in soft start circuit controls the rush current and overshoot of the output voltage when the power
is turned on or the ON/OFF pin is set to “H” level.

Rev.3.0_01
S-8353/8354 Series
3. ON/ OFF Pin (Shutdown Pin) (SOT-23-5 Package Products of A and H Types)
ON/OFF pin stops or starts step-up operation.
Setting the ON/OFF pin to the “L” level stops operation of all the internal circuits and reduces the current
consumption significantly.
DO NOT use the ON/OFF pin in a floating state because it has the structure shown in Figure 10 and is not pulled
up or pulled down internally. DO NOT apply a voltage of between 0.3 V and 0.75 V to the ON/OFF pin because
applying such a voltage increases the current consumption. If the ON/OFF pin is not used, connect it to the VOUT
pin.
The ON/OFF pin does not have hysteresis.

The energy stored in L is represented by 1/2 • L (IPK)2.

(7)
During tON, the energy is stored in L and is not transmitted to VOUT. When receiving the output current (IOUT) from
VOUT, the energy of the capacitor (CL) is consumed. As a result, the pin voltage of CL is reduced, and goes to the
lowest level after M1 is turned ON (tON). When M1 is turned OFF, the energy stored in L is transmitted through the
diode to CL, and the voltage of CL rises rapidly. VOUT is a time function, and therefore indicates the maximum value
(ripple voltage (VP P) ) when the current flowing through into VOUT and load current (IOUT) match.

Next, the ripple voltage is determined as follows.

Figure 12 Relationship between Major Characteristics of Step-up Circuit and External Parts
1. Inductor
The inductance value (L value) has a strong influence on the maximum output current (IOUT) and efficiency (η).
The peak current (IPK) increases by decreasing L value and the stability of the circuit improves and IOUT increases. If L
value is decreased, the efficiency falls causing a decline in the current drive capacity for the switching transistor, and
IOUT decreases.
The loss of IPK by the switching transistor decreases by increasing L and the efficiency becomes maximum at a
certain L value. Further increasing L value decreases the efficiency due to the loss of the direct current resistance of
the coil. IOUT also decreases.
A higher oscillation frequency allows selection of a lower L value, making the coil smaller.
The recommended inductances are a 47 μH to 220 μH for A, C, and D types, a 10 μH to 47 μH for H and J types.
Be careful of the allowable inductor current when choosing an inductor. Exceeding the allowable current of the
inductor causes magnetic saturation, much lower efficiency and destruction of the IC chip due to a large current.
Choose an inductor so that IPK does not exceed the allowable current. IPK in discontinuous mode is calculated by the
following equation:
2IOUT (VOUT + VD − V )
fOSC •L
fosc = oscillation frequency, VD ≅ 0.4 V.

2. Diode
Use an external diode that meets the following requirements :
• Low forward voltage : VF < 0.3 V
• High switching speed : 50 ns max.
• Reverse voltage :
• Current rate :

3. Capacitor (CIN, CL)
A capacitor on the input side (CIN) improves the efficiency by reducing the power impedance and stabilizing the input
current. Select a CIN value according to the impedance of the power supply used.
A capacitor on the output side (CL) is used for smoothing the output voltage. For step-up types, the output voltage
flows intermittently to the load current, so step-up types need a larger capacitance than step-down types. Therefore,
select an appropriate capacitor in accordance with the ripple voltage, which increases in case of a higher output
voltage or a higher load current. The capacitor value should be 10 μF or more.
Select an appropriate capacitor the equivalent series resistance (RESR) for stable output voltage. The stable voltage
range in this IC depends on the RESR. Although the inductance value (L value) is also a factor, an RESR of 30 to
500 mΩ maximizes the characteristics. However, the best RESR value may depend on the L value, the capacitance,
the wiring, and the applications (output load). Therefore, fully evaluate the RESR under the actual operating
conditions to determine the best value.
Refer to the “1. Example of Ceramic Capacitor Application” (Figure 16) in the “ Application Circuit” for the
circuit example using a ceramic capacitor and the external resistance of the capacitor (RESR).
4. VDD / VOUT Separate Type (D and J Types)
The D and J types provides separate internal circuit power supply (VDD pin) and output voltage setting pin (VOUT
pin) in the IC, making it ideal for the following applications.
(1) When changing the output voltage with external resistance.
(2) When outputting a high voltage within the operating voltage (10 V).
Choose the products in the Table 18 according to the applications (1) or (2) above.

Cautions 1. This IC starts a step-up operation at VDD = 0.8 V, but set 1.8 ≤ VDD ≤ 10 V to stabilize the output
voltage and frequency of the oscillator. (Input a voltage of 1.8 V or more at the VDD pin for all
products with a setting less than 1.9 V.) An input voltage of 1.8 V or more at the VDD pin allows
connection of the VDD pin to either the input voltage VIN pin or output VOUT pin.
2. Choose external resistors RA and RB so as to not affect the output voltage, considering that there
is impedance between the VOUT pin and VSS pin in the IC chip. The internal resistance
between the VOUT pin and VSS pin is as follows :
(1) S-835xx18 : 2.1 MΩ to 14.8 MΩ
(2) S-835xx20 : 1.4 MΩ to 14.8 MΩ
(3) S-835xx30 : 1.4 MΩ to 14.2 MΩ
(4) S-835xx50 : 1.4 MΩ to 12.1 MΩ
3. Attach a capacitor (CC) in parallel to the RA resistance when an unstable event such as
oscillation of the output voltage occurs. Calculate CC using the following equation :

Precautions
• Mount external capacitors, diodes, and coils as close as possible to the IC. Especially, mounting the output capacitor
(capacitor between VDD pin and VSS pin for VDD / VOUT separate type) in the power supply line of the IC close to the IC
can enable stable output characteristics. If it is impossible, it is recommended to mount and wire a ceramic capacitor
of around 0.1 μF close to the IC.
• Characteristics ripple voltage and spike noise occur in IC containing switching regulators. Moreover rush current flows
at the time of a power supply injection. Because these largely depend on the coil, the capacitor and impedance of
power supply used, fully check them using an actually mounted model.
• Make sure that the dissipation of the switching transistor (especially at a high temperature) does not exceed the
allowable power dissipation of the package.
• The performance of this IC varies depending on the design of the PCB patterns, peripheral circuits and external parts.
Thoroughly test all settings with your device. The recommended external part should be used wherever possible, but if
this is not possible for some reason, contact an SII Semiconductor Corporation sales person.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• SII Semiconductor Corporation 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 a third party.

corresponding to the RESR in series with the ceramic capacitor (CL) as shown in Figure 16.
R1 differs depending on L value, the capacitance, the wiring, and the application (output load).
