MICROELECTRONICS A A Power Management GM7110 1A STEP-DOWN VOLTAGE SWITCHING REGULATOR Features 3.3V, 5V, 12V, 15V and Adjustable output versions Adjustable version output voltage range 1.23V to 37V ±4% max over line and load conditions 1A output current Requires Only 4 External Components High Efficiency TTL shutdown capability and low power standby mode Thermal shutdown, current limit protection Uses standard inductors 52 kHz fixed frequency internal oscillator Description GM7110 of regulators provides all the active functions for a stepdown (buck) switching regulator, and drives 1A load with excellent line and load regulation. GM7110 is available in fixed output voltages of 3.3V, 5V, 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. GM7110 high-efficiency replacement for popular three-terminal linear regulators, and is requiring a smaller heat sink or even no heat sink. GM7110 performs well with standard inductors from several manufacturers, and simplifying the design of switch-mode power supplies. GM7110 guarantees ±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 µA (typical) standby current. The output switch has cycle-by-cycle current limiting as well as thermal shutdown for full protection under fault conditions.
