Features, Applications

5V, 12V and Adjustable output versions Adjustable version output voltage range 37V ±4% max over line and load conditions 3A output current Input voltage range to 40V Requires only 4 external components High efficiency TTL shutdown capability, low power standby mode Thermal shutdown, current limit protection Uses standard inductors 150 kHz fixed frequency internal oscillator P+ Product Enhancement tested 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 5V, 12V, 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 fixed-frequency oscillator. The GM7230 series are highefficiency 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 switch-mode 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 µA (typical) standby current. The output switch has cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.
