SGM61020
2A High Efficiency
Synchronous Buck Converter
GENERAL DESCRIPTION
FEATURES
The SGM61020 is a high efficiency synchronous Buck
DC/DC converter with 2A output current capability and
adjustable output voltage. The input supply voltage is in
the range of 2.5V to 5.5V. Using adaptive off-time peak
current control, the efficiency of this device is higher
than 80% for loads over 1mA and reaches 95% in the
moderate load ranges (5V to 3.3V).
● 2.5V to 5.5V Input Voltage Range
● Adjustable Output Voltage from 0.6V to VIN
● Up to 95% Efficiency
● Low RDSON MOSFET Switches (100mΩ/55mΩ)
● Power-Save Mode for Light Load Efficiency
● 42μA (TYP) Operating Quiescent Current
● 100% Duty Cycle Capability for Low Dropout
● 1.5MHz PWM Switching Frequency
● Power Good Output (SGM61020P Only)
● Over-Current Protection
This device operates with a quasi-fixed 1.5MHz pulse
width modulation (PWM) mode for moderate or heavy
loads. But at light loads, pulse skip modulation is used
for power-save mode (PSM). The PSM operating
quiescent current is very low, typically 42μA, which is
well suitable for battery-powered applications to
increase standby time. Despite such low quiescent
current, the transient response to large load variations
is excellent. The device shutdown current is typically
0.03μA.
● Thermal Shutdown Protection
● Input Under-Voltage Lockout (UVLO) Protection
● Small Packaging:
SGM61020: Available in Green SOT-23-5 and
SOT-563-6 Packages
SGM61020P: Available in a Green SOT-563-6
Package
The SGM61020 provides an adjustable output voltage
by an external resistor divider. The device is capable for
low dropout operation with 100% duty cycle. Some
other features include internal soft-start for limiting
startup inrush current, over-current and thermal
shutdown protections, enable input and power good
output (for SGM61020P version only).

DETAILED DESCRIPTION
Overview
Power Good Output (SGM61020P Only)
The PG pin is an open-drain output. PG requires a
pull-up resistor (e.g. 510kΩ). PG pin is pulled to GND
before the output voltage is above 95% of the nominal
voltage. After FB voltage reaches 95% of VREF, the PG
pin is pulled high immediately. When the FB voltage
drops below 90% of VREF, the PG pin will be pulled low
after a 45μs delay. Leave the PG pin unconnected
when not used.
The SGM61020 is a high efficiency Buck switching
converter optimized for handheld battery-powered
applications. It operates at a quasi-fixed frequency of
1.5MHz and uses adaptive off-time PWM control for the
moderate to heavy load range. This allows using a
small inductor and small capacitors for compact
designs. At light load condition, this device operates in
power-save mode to reduce the switching frequency
and losses for longer battery life. The power-save
mode quiescent current is 42μA (TYP) while the
shutdown current is only 0.03μA (TYP).

SGM61020
Synchronous Buck Converter
DETAILED DESCRIPTION (continued)
If the load is still low, the output will go slightly higher
than normal again and the switches will be turned off. In
power-save mode, the output voltage is slightly higher
than nominal output voltage. This effect can be
mitigated by a larger output capacitor.
Soft Startup and Pre-biased Output
An 800μs internal soft-start circuit is designed to
prevent input inrush current and voltage drops during
startup. This circuit slowly ramps up the error amplifier
reference voltage (VREF = 0.6V) after exiting the
shutdown state or under-voltage lockout (UVLO). Slow
increase of the output voltage prevents the excessive
inrush current for charging the output capacitors and
creates a smooth output voltage rise. The other
advantage of a soft-start is avoiding supply voltage
drops especially on the high internal impedance
sources such as the primary cells and rechargeable
batteries.
Low Dropout Operation (100% Duty Cycle)
When the input voltage reduces, the on-time increases.
When the input voltage is lower than the regulation
output voltage, the output voltage drops, and the
SGM61020 goes into 100% duty cycle mode. The
high-side switch is always turned on, and the output
voltage is determined by the load current times the
R
DSON composed by the high-side switch and inductor.
The SGM61020 is also capable of starting with a
pre-biased output capacitor when it is powering up or
enabled. When the device is turning on, a bias on the
output may exist due to the other sources connected to
the load(s) such as multi-voltage ICs or simply because
of residual charges on the output capacitors. For
example, when a device with light load is disabled and
re-enabled, the output may not drop during the off
period and the device must restart under pre-biased
output condition. Without the pre-biased capability, the
device may not be able to startup properly. The output
ramp is automatically initiated with the bias voltage and
ramps up to the nominal output value.
Current Limit Protection
Limiting the switch current protects the switch itself and
also prevents over-current in the source and the
inductor. If the high-side (HS) switch current exceeds
the ILIM threshold, HS switch is turned off and the
low-side (LS) switch will be turned on to reduce the
inductor current and limit the peak.
Note that the measured peak current limit in the
closed-loop and open-loop (ILIM_OL) test conditions is
slightly different, mainly due to the current comparator
propagation delay.
Power-Save Mode (PSM)
Thermal Shutdown
At light load condition, the SGM61020 shifts to the PSM
mode and operates with pulse skip modulation to
reduce the switching frequency and minimize the
losses. It also shuts down most of the internal circuits in
PSM. In this mode, one or more PWM pulses are sent
to charge the output capacitor and then the switches
are kept off. The output capacitor voltage gradually
drops due to small load current and when it falls below
the nominal voltage threshold, the PWM pulses resume.
A thermal shutdown function is implemented to prevent
damage caused by excessive heat and power dissipation.
Once the junction temperature exceeds +150°C, the
device is shut down. The device is released from
shutdown automatically when the junction temperature
decreases by 20℃.

Equations 1 and 2 to find the inductor peak current
(IL_MAX) and peak-to-peak ripple current (∆IL) in static

Input Capacitor Selection (CIN)
Use Equation 3 to select the R1/R2 resistor divider to
set the VOUT. Select the R2 value less than 100kΩ to
compromise noise sensitivity and light load losses.
High frequency decoupling input capacitors with low
ESR are needed to circulate and absorb the high
frequency switching currents of the converter. Place
this capacitor right beside the VIN and GND pins. A
4.7μF ceramic capacitor with X5R or better dielectric
and 0805 or smaller size is sufficient in most cases. A

Output Filter Design
This device is capable to operate with low ESR ceramic
capacitors to get low voltage ripple and fast response.
10μF ~ 22μF × 2 capacitors with X7R or X5R dielectric
type are recommended. Minimum capacitance of
output ripple criteria can be calculated from Equation 4.
Table 4 can be used to select the proper LC filter
components for most design requirements. The
inductor initial tolerance can be as high as -30% to +20%
of the nominal value and proper current derating is
usually required. Bias voltage may cause significant
capacitance drops in the ceramic capacitors. The
effective deviation of a ceramic capacitor can be as
high as -50% to +20% of the nominal value.

• Share the same GND return point for the input and
output capacitors and locate it as close as possible
to the device GND pin to minimize the AC current
loops. Place the inductor close to the switching node
and connect it with a short trace to minimize the
parasitic capacitances coupled to the SW node.
