PDF LM5010 Download

Description

The LM5010, step-down switching regulator is an enhanced version of the LM5010 with the input operating range extended to 6-V minimum. The LM5010Ax features all the functions needed to implement a low-cost, efficient, buck regulator capable of supplying in excess of 1-A load current.

Applications

• High Efficiency Point-Of-Load (POL) Regulator
• Non-Isolated Telecommunications Buck Regulator
• Secondary High Voltage Post Regulator
• Automotive Systems

Features

• Input Voltage Range: 8V to 75V
• Valley Current Limit At 1.25A
• Switching Frequency Can Exceed 1 MHz
• Integrated N-Channel Buck Switch
• Integrated Startup Regulator
• No Loop Compensation Required
• Ultra-Fast Transient Response
• Operating Frequency Remains Constant With Load and Line Variations
• Maximum Duty Cycle Limited During Startup
• Adjustable Output Voltage
• Precision 2.5V Feedback Reference
• Thermal shutdown

– Both Packages Have Exposed Thermal Pad For Improved Heat Dissipation
