| The LM2576 series of monolithic integrated circuits provide all the active functions for a step-down (buck) switching regulator. Fixed versions are available with a 3.3V, 5V, or 12V fixed output. Adjustable versions have an output voltage range from 1.23V to 37V. Both versions are capable of driving a 3A load with excellent line and load regulation.Additional Features: 3.3V, 5V, 12V, and adjustable output versions Voltage over specified line and load conditions: Fixed version: ±3% max. output voltage Adjustable version: ±2% max. feedback voltage Guaranteed 3A output current Wide input voltage range: 4V to 40V Wide output voltage range: 1.23V to 37V Requires only 4 external components 52kHz fixed frequency internal oscillator Low power standby mode IQ typically < 200μA 80% efficiency (adjustable version typically > 80%) Uses readily available standard inductors Thermal shutdown and current limit protection 100% electrical thermal limit burn-in Meer informatie: | | Maximum Output Current: | 3A | Maximum Output Voltage: | 12 V | Minimum Input Voltage: | 4 V | Maximum Input Voltage: | 40 V | Output Type: | Fixed | Mounting Type: | Surface Mount | Number of Outputs: | 1 | Maximum Switching Frequency: | 52 kHz | Pin Count: | 5 | Package Type: | TO-263 | Switching Regulator: | Yes | Dimensions: | 0.4 x 0.17 x 0.36in | Height: | 9.14mm | Length: | 10.16mm | Maximum Operating Temperature: | +85 °C |
