HTC KOREA LM2575G
The LM2575G series are monolithic ICs designed for a step-down DC/DC converter, capable of driving 1A load without an additional transistor. The external shutdown function is controlled by a logic level and then the circuit comes into the standby mode. The internal compensation makes the feedback control with good line and load regulation characteristics without an external design.| Part No. | LM2575G |

DESCRIPTION
ORDERING INFORMATION Device Package LM2575GDP-X.X SOP-8PP LM2575GR-X.X TO-263-5L LM2575GT-X.X TO-220-5L X.X = Output Voltage = 3.3. 5.0, 12, ADJ It saves a board space. Regarding the protection functions – the thermal shutdown prevents circuit damage during the over temperature operation and the current limit is against overcurrent operation of the output switch. If the case for the current limiting occurs and VFB is down by 40% of the nominal output voltage, the switching frequency shall be reduced.
