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
