SGM6019
1.2A, 1.6MHz, High Efficiency
Synchronous Step-Down Converter
GENERAL DESCRIPTION
FEATURES
SGM6019 is a high-efficient integrated step-down
regulator with 1.2A guaranteed output current. This
device is capable to provide an input voltage range of
2.7V to 5.5V, making the use of single-cell Li-Ion
battery, three NiMH cells battery or a regulated 5V input
possible.
● 2.7V to 5.5V Input Voltage Range
● 95% Peak Efficiency
● 1.2A Guaranteed Output Current
● 3.7% Output Accuracy Over Temperature
● Programmable Forced PWM Mode and Skip Mode
● 30μA Low Quiescent Current in Skip Mode
● Less than 1μA Shutdown Current
In heavy load condition, this device can work in the
forced pulse width modulation (PWM) mode with a
switching frequency of 1.6MHz (TYP). In addition, it
also can work in the skip mode with 30μA low quiescent
current. The 95% high efficiency at light load allows it to
be highly efficient to conserve the battery life of devices.
Thus, the SGM6019 is specified for the compact
devices with low-voltage microprocessor power supply
requirements. The SGM6019 also includes the features
of internal digital soft-start, peak current limit, short
circuit protection and over-temperature protection.
● 100% Duty Cycle for Lowest Dropout
● Discharge Output Capacitor in Shutdown
● Internal Soft-Start and Peak Current Limit
● Short Circuit and Over-Temperature Protection
● Enable and Power-Good Functions
● Available in a Green TDFN-2×3-8L Package

OVERSTRESS CAUTION
ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.

ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
