1 / 10 page Description 5V, 12V, 15V and a versatile Adjustable output a minimum number of external components. frequency oscillator. replacement for popular three-terminal linear regulators, and is requiring a smaller heat sink or even no heat sink. performs well with standard inductors from several manufacturers, and simplifying the design of switch-mode power supplies. tolerance on output voltage within specified input voltages protection under fault conditions. TYPICAL APPLICATION Features 3.3V, 5V, 12V, 15V and Adjustable version output voltage range 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 7V - 40V Unregulated DC Input + C IN 100 µF +V IN 1 5 3 4 2 GND D1 1N5819 Output 330 µH L1 Feedback C OUT 330 µF 5.0V, 1A Regulated Output + ON / OFF Application Pre-regulator for linear regulators High-efficiency step-down buck regulator On-card/ board switching regulators Positive to negative converter (buck-boost ) of regulators provides all the active functions for a step- down (buck) switching regulator, and drives 1A load with excellent line and load regulation. is available in fixed output volt ages of 3.3V, version. These regulators are simple to use and require Features include internal frequency compensation and a fixed- and output load conditions, and ±10% on the oscillator frequency. External shutdown is included with 50 uA(typical) standby current. The output switch has cycle-by-cycle current limiting as well as thermal shutdown for full 1.23V to 37V ±4% max over line and load conditions Adjustable output versions LM2575 LM2575 LM2575 LM2575 guarantee +/-4% LM2575 high-efficiency LM2575 -5.0 LM2575 1.0A Step - Down Voltage Switching Regulators |
