Details
The LM5005MH is a high-voltage buck converter that offers a complete solution for efficient high-voltage switching regulation. With a wide input voltage range of 7V to 75V and a maximum output current of 2.5A, this converter requires minimal external components for operation. The control loop architecture is based on current-mode control, utilizing an emulated current ramp to ensure high noise immunity. This control method also provides inherent line feed-forward, cycle-by-cycle overcurrent protection, and simple loop compensation. The LM5005MH offers a wide switching frequency range of 50 kHz to 500 kHz, which is resistor-programmable to suit specific application needs

FAQs
What is LM5005MH?
The LM5005MH is a high voltage step-down switching regulator designed by Texas Instruments. It is ideal for applications requiring efficient power conversion from higher input voltages to lower output voltages, such as industrial power supplies, automotive electronics, and distributed power systems.
How Does LM5005MH Work?
The LM5005MH operates as a step-down (buck) switching regulator, converting higher input voltages to lower output voltages with high efficiency. It uses a pulse-width modulation (PWM) control scheme to regulate the output voltage, providing a stable and regulated power supply for the load. The regulator features a wide input voltage range and high frequency operation for compact and efficient power solutions.
How Many Pins does LM5005MH have and What are the Functions of the Pinout Configuration?
The LM5005MH is housed in a 8-pin metal package (TO-220). The pinout configuration includes:
- VIN: Input voltage pin.
- SW: Switching node for the internal MOSFET switch.
- GND: Ground pin.
- FB: Feedback pin for output voltage regulation.
- RT: Timing resistor pin for setting the switching frequency.
- SS/TR: Soft-start/Tracking pin for controlling start-up behavior.
- VCC: Power supply pin for the internal control circuitry.
What are the Pros and Cons of LM5005MH?
Pros:
- High Voltage Conversion: Suitable for converting high input voltages to lower output voltages.
- Efficiency: Provides high efficiency power conversion for energy-conscious applications.
- Wide Input Voltage Range: Accommodates a wide range of input voltages for versatile use.
- Compact Package: The TO-220 package allows for easy heat sinking and thermal management.
Cons:
- External Components: May require additional external components for optimal performance and protection.
- Switching Noise: Switching regulators can introduce noise that may require additional filtering.
Are There Any Equivalents/Alternatives to LM5005MH for Recommendation?
- The LM2675 from Texas Instruments is a similar high voltage step-down switching regulator.
- Alternatives to the LM5005MH include the LT1376 from Analog Devices and the SY8088 from Silergy Corp.
