詳細說明
SG6846ALSZ emerges as a standout low dropout voltage regulator that can handle a continuous output current of up to 850 mA. The noteworthy feature of this regulator is its minimal dropout voltage of only 350 mV at a 500 mA output, ensuring efficient power conversion, especially in scenarios where maintaining voltage levels is vital. The regulator's fixed output voltage of 3.3V makes it a versatile choice for diverse applications requiring a stable power source. To enhance operational safety, SG6846ALSZ incorporates thermal shutdown and current limit protection, offering defense against potentially damaging conditions like overheating and excessive current draw. Furthermore, the presence of a shutdown pin enables convenient power management, enabling users to power down the regulator when not in use and thereby conserving energy. Encased in a compact SOP-8 package, the SG6846ALSZ is well-suited for space-constrained electronic designs demanding high performance within a compact footprint

常見問題解答
What is SG6846ALSZ?
The SG6846ALSZ is a dual-step-down, high-efficiency synchronous buck regulator designed by Sanken Electric. It is suitable for applications requiring voltage regulation and power efficiency, such as DC-DC converters, power supplies, and battery chargers.
How Does SG6846ALSZ Work?
The SG6846ALSZ operates as a dual-step-down synchronous buck regulator, converting high input voltage to a lower regulated output voltage with high efficiency. It utilizes pulse-width modulation (PWM) control to adjust the duty cycle of the output voltage, providing stable power supply output.
How Many Pins does SG6846ALSZ have and What are the Functions of the Pinout Configuration?
The SG6846ALSZ is housed in a 12-pin SIP (Single In-Line Package) package. The pinout configuration includes:
- VIN: Input voltage pin.
- GND: Ground pin.
- SW1, SW2: Switching pins for the two buck regulators.
- FB1, FB2: Feedback pins for voltage regulation.
- EN1, EN2: Enable pins for each regulator.
- PSON: Power-on sequence control pin.
- PGND: Power ground pin.
- VCC: Voltage supply pin.
What are the Pros and Cons of SG6846ALSZ?
Pros:
- High Efficiency: Achieves high efficiency in voltage conversion, reducing power loss.
- Dual-Channel Operation: Provides two independent buck regulators in a single package for flexible power supply design.
- Wide Input Voltage Range: Supports a wide input voltage range for versatile application compatibility.
- Overcurrent Protection: Includes overcurrent protection features for reliable operation.
- Compact Package: The 12-pin SIP package is space-efficient, suitable for compact designs.
Cons:
- External Components: May require additional external components for filtering and protection in certain applications.
- Temperature Considerations: Thermal management may be necessary to maintain optimal operation under high load conditions.
Are There Any Equivalents/Alternatives to SG6846ALSZ for Recommendation?
- The LM22672 from Texas Instruments is a comparable dual-step-down buck regulator.
- Alternatives to the SG6846ALSZ include the LT8612 from Analog Devices and the MP2036 from Monolithic Power Systems.
