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
