www.DataSheet4U.com GM7230 3A STEP-DOWN VOLTAGE REGULATOR Power Management 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 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 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 µA (typical) standby current. The output switch has cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions. Features 3.3V, 5V, 12V and Adjustable output versions Adjustable version output voltage range 1.23V to 37V 4% max over line and load conditions 3A output current Input voltage range up to 40V Requires only 4 external components High efficiency TTL shutdown capability, low power standby mode Thermal shutdown, current limit protec...
