General Description<\/h3>\n\n\n\n

EGM2576 series is designed to provide all the active function for a step-down (buck)switching regulator, and drives a maximum load current as high as 3A line and load regulations.<\/p>\n\n\n\n

EGM2576 is available in fixed output voltages of 3.3V, 5V, and a versatile Adjustable output version.<\/p>\n\n\n\n

These regulators are simple to use and require minimum number of external components.<\/p>\n\n\n\n

The features include internal frequency compensation and a fixed-frequency oscillator.<\/p>\n\n\n\n

The EGM2576 is high-efficiency replacements for popular three-terminal linear regulators,and is requiring a smaller heat sink or even no need heat sink.<\/p>\n\n\n\n

EGM2576 performs well with standard inductors from most of manufacturers, and simplifying the design of switch-mode power supplies.<\/p>\n\n\n\n

External shutdown is included with 80 \u00b5A (typical) standby current.<\/p>\n\n\n\n

The output switch has cycle-by-cycle current limiting as well as thermal shutdown for full protection under fault conditions.<\/p>\n\n\n\n

EGM2576 operates at a switching frequency of 52 kHz which allowing smaller size filter components than what would be needed with lower frequency switching regulators.<\/p>\n\n\n\n

EGM2576 series are available in a standard 8 lead SOP package with heat sink<\/p>\n\n\n\n
