General Description
GM7230-ATB5T General Description
The GM7230 series of regulators provide all the active functions for a step-down (buck) switching regulator, and drive 3A load with excellent line and load regulation. GM7230's are available in fixed output voltages of 3.3V, 5V, 12V, and a Adjustable output version.
These regulators are simple to use and require a minimum number of external components. Features include internal frequency compensation and a fixed-frequency oscillator.
The GM7230 series are high-efficiency replacements for popular three-terminal linear regulators, requiring a smaller heatsink or even no heatsink.
The GM7230's perform well with standard inductors from several manufacturers, simplifying the design of switchmode power supplies. The GM7230 series guarantee ±4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency.
External shutdown is included, with 80 A (typical) standby current. The output switch has cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.
