Pre-regulator for linear regulators High-efficiency step-down buck regulator On-card/board switching regulators Positive to negative converter (buck-boost)

The GM7130 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. GM7130's are available in fixed output voltages 12V, 15V, and a versatile Adjustable output version. These regulators are simple to use and require a minimum number of external components. Features include internal frequency compensation and a fixedfrequency oscillator. The GM7130 series are highefficiency replacements for popular three-terminal linear regulators, requiring a smaller heatsink or even no heatsink. The GM7130's perform well with standard inductors from several manufacturers, simplifying the design of switch-mode power supplies. The GM7130 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 50 �A (typical) standby current. The output switch has cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.
