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  
APPLICATIONS
