Rev.1.4_00
The S-85S1A Series introduces own distinctive low power consumption control and COT (Constant On-Time) control and
features ultra low current consumption and fast transient response. PWM / PFM switching control automatically switches to
PFM control when under light load, and the IC operates at ultra low current consumption of 260 nA quiescent current. The
S-85S1A Series realizes high efficiency in a wide range of load current consumption and provides strong support for
extended period operation of mobile devices and wearable devices which are equipped with compact batteries.
The S-85S1A Series can configure a step-down regulator only with a coil, an input capacitor, and an output capacitor. By
using external parts recommended in this datasheet, the occupancy area can be reduced to 2.0 mm × 4.5 mm = 9.0 mm2,
and it contributes to miniaturization of electronic equipment.

S-85S1A Series
Rev.1.4_00
Operation
1. Fast transient response
Distinctive COT (Constant On-Time) control is used for DC-DC converter control.
The S-85S1A Series monitors the output voltage (VOUT) using a comparator and if VOUT falls below the targeted
value, the high side power MOS FET will turn on for a certain amount of time. Since the high side power MOS FET
turns on and VOUT rises immediately after the load current fluctuates rapidly and VOUT falls, the fast transient
response is realized.
The S-85S1A Series outputs ON time in proportion to VOUT and in inverse proportion to power supply voltage.
Therefore, when in continuous mode, even if the power supply voltage or VOUT settings would change, it always
operates at a quasi-fixed frequency of 1 MHz.
2. PWM / PFM switching control
The S-85S1A Series automatically switches between the pulse width modulation method (PWM) and pulse
frequency modulation method (PFM) according to the load current. If the output current (IOUT) is large, the IC will
operate at PWM control. If IOUT is small, the IC will operate at PFM control and the pulse will skip according to the
load current. This reduces switching loss and improves efficiency when under light load.
The S-85S1A Series has a built-in reverse current detection circuit. The reverse current detection circuit monitors
the current flowing through the inductor. If the bottom of ripple current in the inductor falls to 0 mA, the high side
power MOS FET and low side power MOS FET will turn off and switching operation will stop. Switching frequency
will fall from 1.0 MHz by skipping a pulse. This means that the smaller IOUT is, the more the switching frequency (fSW
will drop, and it reduces switching loss.
)
3. Ultra low current consumption
When in discontinuous mode, the S-85S1A Series reduces current consumption to 260 nA typ. by intermittently
operating a control circuit and a protection circuit. When under light load, the high side power MOS FET and low
side power MOS FET will turn off. When switching operation stops and a certain amount of time elapses, only the
necessary circuits will operate.
Under voltage lockout function (UVLO), thermal shutdown function, current limit function, and automatic recovery
type short-circuit protection function are prepared in the S-85S1A Series, and each protection function will carry out
detection operation for a certain amount of time from when the high side power MOS FET turns on under light load.
It is thus able to realize ultra low current consumption. When under heavy load, the IC changes to continuous mode
as a result of the fact that the high side power MOS FET and low side power MOS FET turn on continuously, so all
the IC, including the protection circuits, will operate.
4. EN pin
This pin starts and stops switching operation. When the EN pin is set to "L", the operation of all internal circuits,
including the high side power MOS FET, is stopped, reducing current consumption. Current consumption increases
when a voltage of 0.3 V to VIN − 0.3 V is applied to the EN pin. When not using the EN pin, connect it to the VIN pin.
Since the EN pin is neither pulled down nor pulled up internally, do not use it in the floating status. The structure of
the EN pin is shown in Figure 3.

5. Under voltage lockout function (UVLO)
The S-85S1A Series has a built-in UVLO circuit to prevent the IC from malfunctioning due to a transient status at
power-on or a momentary drop in the supply voltage. When UVLO status is detected, the high side power MOS FET
and low side power MOS FET will turn off, and the SW pin will change to "High-Z". For this reason, switching
operation will stop. The soft-start function is reset if UVLO status is detected once, and is restarted by releasing the
UVLO status.
Note that the other internal circuits operate normally and the status is different from the disabled status.
Also, there is a hysteresis width for avoiding malfunctions due to generation of noise etc. in the input voltage.
6. Thermal shutdown function
The S-85S1A Series has a built-in thermal shutdown circuit to limit overheating. When the junction temperature
increases to 135°C typ., the thermal shutdown circuit becomes the detection status, and the switching operation is
stopped. When the junction temperature decreases to 115°C typ., the thermal shutdown circuit becomes the release
status, and the switching operation is restarted.
If the thermal shutdown circuit becomes the detection status due to self-heating, the switching operation is stopped
and output voltage (VOUT) decreases. For this reason, the self-heating is limited and the temperature of the IC
decreases. The thermal shutdown circuit becomes release status when the temperature of the IC decreases, and
the switching operation is restarted, thus the self-heating is generated again. Repeating this procedure makes the
waveform of VOUT into a pulse-like form. Switching operation stopping and starting can be stopped by either setting
the EN pin to "L", lowering the output current (IOUT) to reduce internal power consumption, or decreasing the ambient
temperature.

7. Overcurrent protection function
The S-85S1A Series has a built-in current limit circuit.
The overcurrent protection circuit monitors the current that flows through the low side power MOS FET and limits
current to prevent thermal destruction of the IC due to an overload, magnetic saturation in the inductor, etc.
When a current exceeding the current limit (ILIM) flows through the low side power MOS FET, the current limit circuit
operates and prohibits turning on the high side power MOS FET until the current falls below the low side current limit
(ILIMDET). If the value of the current that flows through the low side power MOS FET falls to the ILIMDET or lower, the
S-85S1A Series returns to normal operation. ILIMDET is fixed at 270 mA typ. in the IC, and ILIM will vary depending on
the external parts to be used.
The relation between ILIM, the inductor value (L), the input voltage (VIN), and the output voltage (VOUT) are shown in
the following expression.

8. Automatic recovery type short-circuit protection function (Hiccup control)
The S-85S1A Series has a built-in automatic recovery type short-circuit protection function for Hiccup control.
Hiccup control is a method for periodically carrying out automatic recovery when the IC detects overcurrent and
stops the switching operation.

9. Pre-bias compatible soft-start function
The S-85S1A Series has a built-in pre-bias compatible soft-start circuit.
If the pre-bias compatible soft-start circuit starts when electrical charge remains in the output voltage (VOUT) as a
result of power supply restart, etc., or when VOUT is biased beforehand (pre-bias status), switching operation is
stopped until the soft-start voltage exceeds the internal feedback voltage, and then VOUT is maintained. If the
soft-start voltage exceeds the internal feedback voltage, switching operation will restart and VOUT will rise to the
output voltage setting value (VOUT(S)). This allows VOUT(S) to be reached without lowering the pre-biased VOUT
.
In soft-start circuits which are not pre-bias compatible, a large current flows as a result of the discharge of the
residual electric charge through the low side power MOS FET when switching operation starts, which could cause
damage, however in a pre-bias compatible soft-start circuit, the IC is protected from the large current when switching
operation starts, and it makes power supply design for the application circuit simpler.
In the S-85S1A Series, VOUT reaches VOUT(S) gradually due to the soft-start circuit.
In the following cases, rush current and VOUT overshoot are reduced.
• At power-on
• When the EN pin changes from "L" to "H".
• When UVLO operation is released.
• When thermal shutdown is released.
• At short-circuit recovery
In addition, the soft-start circuit operates under the following conditions.
The soft-start circuit starts operating after "H" is input to the EN pin and the soft-start wait time (tSSW) = 1.5 ms typ.
elapses. The soft-start time (tSS) is set to 1.0 ms typ.
• At power supply restart (the IC restart)
• At UVLO detection (after UVLO release)
• At thermal shutdown detection (after thermal shutdown release)
• After Hiccup control

1. Input capacitor (CIN)
CIN can lower the power supply impedance, average the input current, improve the efficiency and noise tolerance.
Select a capacitor according to the impedance of the power supply to be used. Also take into consideration the DC
bias characteristics of the capacitor to be used.
2. Output capacitor (COUT
)
COUT is used to smooth output voltage. If the capacitance is large, the overshoot and undershoot during load
transient and output ripple voltage can be improved even more. Select a proper capacitor after the sufficient
evaluation under actual conditions.

3. Inductor (L)
When selecting L, note the allowable current. If a current exceeding this allowable current flows through the inductor,
magnetic saturation may occur, and there may be risks which substantially lower efficiency and damage the IC as a
result of large current.
Therefore, select an inductor so that peak current value (IPK), even during overcurrent detection, does not exceed
the allowable current.
When prioritizing the load response, select an inductor with a small L value such as 2.2 μH. When prioritizing the
efficiency, select an inductor with a large L value such as 10 μH. IPK is calculated using the following expression.

Board Layout Guidelines
Note the following cautions when determining the board layout for the S-85S1A Series.
• Place CIN as close to the VIN pin and the PVSS pin as possible.
• Make the VIN pattern and GND pattern as wide as possible.
• Place thermal vias in the GND pattern to ensure sufficient heat dissipation.
• Keep thermal vias near CIN and COUT approximately 3 mm to 4 mm away from capacitor pins.
• Large current flows through the SW pin. Make the wiring area of the pattern to be connected to the SW pin small to
minimize parasitic capacitance and emission noise.
• Do not wire the SW pin pattern under the IC.
Total size 2.0 mm × 4.5 mm = 9.0 mm2
Figure 8 Reference Board Pattern
Caution The above pattern diagram does not guarantee successful operation. Perform thorough evaluation
using the actual application to determine the pattern.
Remark Refer to the land drawing of SNT-6A and "SNT Package User's Guide".

Precautions
•
•
Mount external capacitors and inductors as close as possible to the IC, and make single GND.
Characteristic ripple voltage and spike noise occur in the IC containing switching regulators. Moreover rush current
flows at the time of a power supply injection. Because these largely depend on the inductor, the capacitor and
impedance of power supply to be used, fully check them using an actually mounted model.
•
The 10 μF capacitor connected between the VIN pin and the VSS pin is a bypass capacitor. It stabilizes the power
supply in the IC when application is used with a heavy load, and thus effectively works for stable switching
regulator operation. Allocate the bypass capacitor as close to the IC as possible, prioritized over other parts.
•
•
•
Although the IC contains a static electricity protection circuit, static electricity or voltage that exceeds the limit of
the protection circuit should not be applied.
The power dissipation of the IC greatly varies depending on the size and material of the board to be connected.
Perform sufficient evaluation using an actual application before designing.
