Frequently Asked Questions
What is the HV designation in LM2575HV?
HV means High Voltage input. The standard LM2575 supports up to 40V input, while the LM2575HV extends the maximum input to 60V. Choose the HV version for 48V industrial bus or automotive applications with high voltage transients.
What external components does LM2575 need?
The LM2575 requires only 4 external components: an input capacitor (100µF), an output capacitor (330µF), a catch diode (1N5822 Schottky), and an inductor (330µH). All component values are specified in the datasheet for each output voltage.
What efficiency does LM2575 achieve?
At 12V input to 5V output with 1A load, LM2575 achieves approximately 77% efficiency. With higher input voltages (24V, 48V), efficiency decreases due to the fixed 52kHz frequency. For higher efficiency needs, consider TI's newer SIMPLE SWITCHER products.
Can LM2575 replace a 7805 linear regulator?
Yes, the LM2575-5.0 is a direct efficiency upgrade from 7805 linear regulators. At 12V input/1A, a 7805 wastes 7W as heat while the LM2575 wastes only about 1.5W. The TO-220 form factor allows physical retrofit in many existing designs.
