DETAILED DESCRIPTION
cycle which ultimately regulates the output voltage to
the desired voltage. At the beginning of each clock
cycle, the PWM comparator turns on the low-side
MOSFET to ramp up the inductor current. As the
inductor current reaches the level set by the error
amplifier’s output, the low-side MOSFET turns off,
which causes the external Schottky diode to be forward
biased to ramp down the inductor current that delivers
the energy to the load as well as replenishes the output
capacitor.
Operation
The SGM6623 is a miniature Boost converter with
integrated low-side MOSFET switch, which is capable
of delivering up to 13V output voltages that are typically
used in battery operated portable devices. Current
mode PWM control is used to regulate the output
voltage as shown in Figure 2. The device has a fixed
switching frequency of 600kHz (TYP). A slope ramp is
added to the sensed peak current ramp to avoid
sub-harmonic oscillation at operation duty cycle higher
than 40%. The error amplifier compares the FB pin
voltage with an internal reference signal to provide an
error signal for the PWM comparator to adjust the duty

DETAILED DESCRIPTION (continued)
The SGM6623 monitors the voltage at the SW pin
during each switching cycle. The circuitry turns off the
switch FET when the SW voltage exceeds the OVP
threshold. The switch FET remains in shutdown mode
until SW pin voltage is lower than 13.37V for 100ms.
The OVP threshold of SGM6623 is 13.8V.
Soft-Start
The SGM6623 implements the internal soft-start
feature to reduce the inrush current drawn during
start-up. When logic high is applied on the EN pin, the
device starts operation and ramps up the reference
voltage to 1.205V in 2.5ms. The 2.5ms soft-start time
ensures the output voltage to ramp slowly, which
effectively reduces the inrush current during start-up.
Pulse-Skipping Mode
The SGM6623 integrates a pulse-skipping mode at the
light load. When a light load condition occurs, the
EAOUT voltage naturally decreases and reduces the
peak current. When the EAOUT voltage further goes
down with the load lowered and reaches the pre-set low
threshold, the output of the error amplifier is clamped at
this threshold and does not go down any more. If the
load is further lowered, the output voltage of SGM6623
exceeds the nominal voltage and the device skips the
switching cycles. The pulse-skipping mode reduces the
switching losses and improves efficiency at the light
load condition by reducing the average switching
frequency.
As shown in Figure 1, the VS pin is the power input for
the device itself and is powered from the converter
output or a voltage source in proper range. When the
VS pin is powered from the converter output, before
enabling the chip, the bias to VS comes from the input
through the inductor and Schottky diode. The
SGM6623 can start up from input voltage as low as
1.5V. During start-up, the controller switches the
N-channel MOSFET continuously until the VOUT
reaches 2.7V. When 2.7V is reached, the normal Boost
regulator feedback takes over the control. Once the
device is in the regulated state, it can work when the
input voltage drops to 0.8V.
When the VS is not self-biased with its own output but
from an independent power source, enable the device
after the VS is biased > 3V stably to avoid continuous
switching without output voltage regulation, in which the
output voltage may trigger the over-voltage protection
and hiccups to output the maximum possible voltage
decided by the OVP threshold.
Enable and Shutdown
The SGM6623 implements the EN function to turn
on/off the device. A logic signal lower than 0.3V turns
off the device. The EN pin integrates an internal 570kΩ
(TYP) pull-down resistor to prevent the device from
false turn-on when the EN pin is left floating. Apply two
levels logic or analog bias with edge slope rate >
10V/ms to enable/shutdown the device stably. Quick
toggles during the enabling may cause false
over-voltage hiccup if the bias voltage ramps slowly.
Over-Current Protection
The SGM6623 provides inherent over-current
protection. The low-side MOSFET is turned off when
the peak current reaches the current limit threshold of
4.4A (TYP), and the low-side MOSFET is not turned on
again until the next clock cycle.
Thermal Shutdown
The internal thermal shutdown protection turns off the
device when the junction temperature exceeds 165℃.
The chip will resume operation when the junction
temperature drops by at least 15℃ (TYP).
Over-Voltage Protection (OVP)
Over-voltage protection circuitry prevents IC damage
as the result of output resistor divider disconnection.

APPLICATION INFORMATION
DC current can be calculated by subtracting half of the
inductor ripple current from the current limit value. The
inductor ripple current is a function of the switching
frequency, inductor value and duty cycle. In summary,
the following two equations show the impact of all the
above factors on the maximum output current.
Supply to Internal Circuit
The internal circuit is biased from the VS pin. The bias
voltage could be from 3V to 12V, but not higher than the
output voltage + 1V, which could be connected to the
VOUT or to any supply rail whose voltage is in the
range as mentioned above. But when the supply rail is
less than 3V, the voltage of EN must be less than 0.3V.
When the VS pin is connected to the VOUT, a 50Ω
resistor inserted between VS and VOUT is
recommended to isolate the VS from potential voltage

Maximum Output Current
The SGM6623 also implements minimum on-time
switching pulse width, which is related to the minimum
duty cycle. In light load condition, the device enters
pulse-skipping mode, and the device operates with
minimum duty cycle in this mode.
For the Boost converter, the maximum input current is
generally limited by the over-current limit. And the
maximum input power (for a given input voltage) is also
limited by the over-current limit. Therefore, the
maximum output power is limited to the maximum input
power minus losses. So, the actual maximum output
current depends on the input current limit, input voltage,
output voltage and efficiency. The input current limit
clamps the peak inductor current. The maximum input

input voltage ripple and reduced efficiency. Large
Inductor Selection
inductors with low DCR values can offer better output
current and higher conversion efficiency. However,
smaller inductance usually provides better load
transient response. For these reasons, an inductance
with 30%~40% current ripple (of the peak load current) is
recommended.
Inductor is the most critical component in the design of
a Boost converter with SGM6623 because it affects
steady state operation, transient behavior and loop
stability (sub-harmonic oscillations). Four parameters of
the inductor must be considered in the design: nominal
inductance value, DC resistance (DCR), saturation
current (or 20%~30% inductance-drop currents) and
maximum RMS current (DC plus AC) for a certain
temperature rise.
SGM6623 implements built-in slope compensation to
prevent sub-harmonic oscillation. Too small inductance
might result in insufficient slope compensation, which
ultimately results in unstable operation. Therefore, the
designer must verify the selected inductor for the
application with the maximum and minimum margins of
the input and output voltages if it is not chosen based
on the recommended values.
Inductance and saturation current of an inductor are the
two most important criterions for the inductor selection.
It is recommended to choose a peak-to-peak ripple
current (given by Equation 2) that is in the 30%~40%
range of the maximum DC current of the inductor in the
application. Such ripple factor usually gives a good
compromise between inductor core and converter
conduction losses (due to the ac ripple) and the
inductor size. Inductor DC current can be calculated
based on input-output power balance as given in
Equation 5:
Schottky Diode Selection
The external rectification diode selection is critical to
ensure device performance. A high speed and low
forward voltage drop diode is recommended to improve
efficiency. The average current rating of the diode
should be higher than the peak load. The breakdown
voltage of the selected diode should be higher than the
maximum output voltage (13V) with margin. To achieve
smaller size and less cost, Schottky diodes with lower
rated voltages can be used. For example, a 12V output
application requires a minimal of 20V breakdown
voltage.

IN_DC

Typically, the inductor value can have a ±20% initial
tolerance. On top of that the inductance may drop
another 20%~30% when the inductor current
approaches to the maximum (saturation or 20%~30%
drops) at maximum current. This drop is usually given
by manufacturer. Note that the powder iron core
inductors do not have a sharp saturation like ferrite
inductors and show a gradual inductance drop even if
the current peaks are much higher than their maximum
rated currents, which is an important advantage. The
manufacturer specifies the 20%~30% drop current level
for them instead of saturation. However, they are
usually slightly bigger than the similar ferrite inductor.
Finally, the total RMS current of the inductor must be
limited to keep the total inductor losses low and prevent
excessive temperature rise in the inductor. The DCR of
an inductor may increase around 50% if the
temperature is increased from +25℃ to +125℃. Such
temperature rises need to be considered in the
evaluation of the I2R losses of the inductor.
Input and Output Capacitor Selection
The output capacitors of Boost converter dictate the
output voltage ripple and load transient response.
Equation 6 is used to estimate the necessary
capacitance to achieve desired output voltage ripple,
where VRIPPLE is the peak-to-peak output ripple.

The additional output ripple component caused by ESR
can be given by Equation 7.
(7)
VRIPPLE_ESR = ΔIL ×ESR
For ceramic capacitors, the ESR is usually small and
VRIPPLE_ESR can be neglected, but for tantalum or
electrolytic capacitors, the capacitive and ESR
components of the ripple must be added to estimate the
total output voltage ripple.
Using an inductor with a smaller inductance in a Boost
converter results in having discontinuous conduction
mode (DCM) range extended to the higher load
currents due to larger ripple. Small inductance can also
result in reduced maximum output current, increased
