General Description

EGM2576HV 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.

EGM2576HV is available in fixed output voltages of 3.3V, 5V, and a versatile Adjustable output version.

These regulators are simple to use and require minimum number of external components.

The features include internal frequency compensation and a fixed-frequency oscillator.

The EGM2576HV is high-efficiency replacements for popular three-terminal linear regulators, and is requiring a smaller heat sink or even no need heat sink.

EGM2576HV performs well with standard inductors from most of manufacturers, and simplifying the design of switch-mode power supplies. External shutdown is included with 80 µA (typical) standby current.

The output switch has cycle-by-cycle current limiting as well as thermal shutdown for full protection under fault conditions.

EGM2576HV operates at a switching frequency of 52 kHz which allowing smaller size filter components than what would be needed with lower frequency switching regulators.

EGM2576HV series are available in a standard 8 lead SOP package with heat sink
