常見問題解答
What is HV9120NG-G?
The HV9120NG-G is a 1.5A, 26V step-down switching regulator designed by Supertex. It is ideal for applications requiring efficient power conversion in a compact and cost-effective solution, such as power supplies, LED drivers, and portable devices.
How Does HV9120NG-G Work?
The HV9120NG-G operates as a step-down 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 power supply for various applications. The regulator features overcurrent protection and thermal shutdown for added reliability.
How Many Pins does HV9120NG-G have and What are the Functions of the Pinout Configuration?
The HV9120NG-G is housed in a 5-lead TO-220 package. The pinout configuration includes:
- VIN: Input voltage pin.
- VOUT: Output voltage pin.
- GND: Ground pin.
- Feedback (FB): Feedback pin for controlling the output voltage.
- Enable (EN): Enable pin for turning the regulator on or off.
What are the Pros and Cons of HV9120NG-G?
Pros:
- High Efficiency: Provides efficient power conversion for extended battery life and reduced heat dissipation.
- Compact Package: The TO-220 package offers a rugged and space-saving solution for power supply designs.
- Overcurrent Protection: Includes overcurrent protection for added reliability in various load conditions.
- Low Dropout Voltage: Enables operation with low input-output differentials for extended battery life.
Cons:
- External Components: May require external components such as inductors and capacitors for optimal operation.
- Heat Dissipation: The TO-220 package may require additional heat sinking for high power applications.
Are There Any Equivalents/Alternatives to HV9120NG-G for Recommendation?
- The LM2675 from Texas Instruments is a similar 1A step-down switching regulator with a wide input voltage range.
- Alternatives to the HV9120NG-G include the MC34063A from ON Semiconductor and the TPS5430 from Texas Instruments.
