SGM61013
10MHz, 1A Micro-Point-of-Load Buck Converter
GENERAL DESCRIPTION
FEATURES
The Micro-Point-of-Load (µPOL) SGM61013 is a family
of high-efficient and high-frequency Buck DC/DC
converter. Operating with a switching frequency up to
10MHz, it allows the use of small external components
in both value and footprint. Different versions are
available with fixed output voltages of 1.2V, 1.8V and
3.3V, delivered from an input voltage supply of 2.3V to
5.5V. A low quiescent current of only 20µA (TYP)
enables high efficiency even with very light loads.
● 2.3V to 5.5V Input Voltage Range
● SGM61013A: 1.8V Fixed Output Voltage
● SGM61013B: 1.2V/3.3V Fixed Output Voltages
● 1A Output Current
● 20μA (TYP) Quiescent Current
● Up to 95% Efficiency
● Selectable PFM Light Load Operation
● Fast Load Transient Response
● 100% Duty Cycle
● Logic Enable Input
● Soft-Start
● Input Under-Voltage Lockout
● Over-Current Protection
● Thermal Shutdown
At light current load condition, the converter will
automatically enter pulse frequency modulation (PFM)
mode for best possible efficiency over the entire range
of load currents. If PFM mode is not desired, the MODE
pin can be set high to forced pulse width modulation
(FPWM) operation.
● Active Output Discharge
● Available in a Green WLCSP-0.9×1.2-6B Package

SGM61013
10MHz, 1A Micro-Point-of-Load Buck Converter
DETAILED DESCRIPTION
The SGM61013 family is synchronous Buck DC/DC
converters with switching frequency up to 10MHz.
Operating from an input voltage between 2.3V and 5.5V,
the converter can deliver up to 1A load current at a
fixed output voltage.
operates in pulse width modulation (PWM) mode
regardless of load current. The PWM mode is a
continuous switching mode where the duty cycle is
modulated to achieve the required output power.
When connected to logic low, the converter
automatically switches to pulse frequency modulation
(PFM) mode at light current loads. In PFM mode the
frequency of pulses is varied to deliver the best
possible efficiency. The device switches between PFM
and PWM as the load current changes and thus
optimizes performance.
Under-Voltage Lockout (UVLO)
The under-voltage lockout feature prevents the device
from turning on if VIN is below the UVLO level of 2.0V. If
the device is enabled under UVLO conditions, the
circuitry will not turn on until the input voltage is
increased. Once it is active, the UVLO circuit has
150mV of hysteresis and the device will turn off if VIN
drops below 1.85V.
If the input voltage ever gets too close to the target
output voltage, such that regulation can no longer be
maintained, the converter will enter 100% duty cycle
mode. In this mode the high-side switch is on,
connecting the input and output together to deliver a
voltage as close to the target as possible.
Enable
Setting the EN voltage to logic high enables the device.
Alternatively, the device is disabled when the EN
voltage is set to logic low. In this state, the IC draws
less than 1µA of current and the output is pulled down
to ground through a resistive load (RDSON). VOUT starts
to ramp up after 100µs delay.
Over-Current Protection
The device has an over-current protection to prevent
damage to the device and inductor during over-current
conditions.
Soft-Start
When the device is enabled, internal soft-start circuitry
causes VOUT to ramp up over a period of 280µs to limit
inrush current. This feature protects a high impedance
source from being pulled to a lower voltage as the
device turns on.
Over-current protection occurs at 1.6A. After hitting 16
consecutive cycles of peak current limit, the output will
be disabled. After being disabled for 1.5ms, the device
will be re-enabled, and a new soft-start cycle will begin.
Thermal Shutdown
Active Output Discharge
The device thermal shutdown protection is enabled if
the chip temperature exceeds +135 ℃ . Once the
temperature drops below +120℃, the device will be
re-enabled, and a new soft-start cycle will begin.
When the device is disabled through the EN pin, a
discharge path for the output capacitor is created
between VOUT and ground through a 17Ω resistor (RDIS).
Modes of Operation
The MODE pin selects the device’s mode of operation.
When connected to logic high, the converter always

away from SW and inductor.
Poor layout could result in system instability, EMI failure,
and device damage. Hence, care must be taken in
board layout to achieve the specified performance.
Please use the following guidelines when designing
PCBs:
● Keep components placement as compact as
possible.
● Place a low-ESR input capacitor as close to VIN and
GND as possible.
● Minimize the area between SW pin trace and inductor
to limit high frequency radiation.
● Keep FB trace away from noisy components and
traces (e.g. SW and inductor).
● Use wide and short traces for the main current paths.
● Ground pins of converter must be strongly
connected to PCB ground with low inductance and
impedance.
