LM5007SD Typical application Circuitry

LM5007SD

The LM5007SD is a high voltage switching regulator by Texas Instruments. This device presents a highly-efficient solution for systems requiring voltage conversions.

LM5007SD Features:

1. Broad Input Range: The LM5007SD caters to an input voltage range of 6V to 75V, making it applicable in diverse environments.

2. Adjustable Output Voltage: By using external components, the output voltage of the LM5007SD can be adjusted, affording design flexibility.

3. Switching Frequency: It supports up to 500 kHz of programmed switching frequency.

4. Protection Measures: The LM5007SD provides various safety features such as thermal shutdown, under-voltage lockout, and cycle-by-cycle current limit for a secure operation.

LM5007SD Application Scenarios:

The LM5007SD suits applications in a range of fields like industrial control systems, automotive systems, telecommunications, and power supply designs.

Detailed Circuit Connection - Power Supply Design Example:

- Pin 1 (VIN): This pin connects to the power source within the 6V to 75V range, serving as the input voltage pin.

- Pin 3 (RT): By connecting a resistor from this pin to the ground, you can adjust the oscillator's frequency.

- Pin 4 (FB): Known as the feedback pin, this is connected to a resistor divider network from the output voltage to the ground to determine the required output voltage.

- Pin 6 (COMP): This compensation pin is connected to the error amplifier's output.

- Pin 7 (VCC): Providing the drive for the output stage, this pin should be connected to a capacitor that links to the ground.

- Pin 8 (GND): As the ground pin, it connects to the system ground.

Design Considerations:

1. Inductor Selection: Picking the correct inductor value is critical for the LM5007SD to operate stably and efficiently. The inductor value must lie within the range recommended in the datasheet.

2. Thermal Management: The LM5007SD requires proper thermal management to ensure a reliable operation, particularly in high-power applications.

3. PCB Layout: The performance of the LM5007SD depends on a well-designed PCB layout. The critical high current paths must be kept short and wide to minimize parasitic inductance and resistance.

In conclusion, the LM5007SD provides an efficient, versatile solution for systems necessitating a high-voltage switching regulator. Its wide input range and adjustable switching frequency make it flexible for multiple applications, and with careful design considerations, it can operate reliably and efficiently.
