Details
The PM6686 also includes a selectable switching frequency option, allowing for customization with three different values for the two switching sections. Additionally, an embedded linear regulator delivers either 3.3 V/5 V output or an adjustable voltage ranging from 0.7 V to 4.5 V, capable of supplying up to 100 mA output current. The presence of an optional external charge pump monitoring feature adds to its versatility. Furthermore, the PM6686 supports a switchover function, enabling the bypass of the LDO output with the switching regulator outputs or an external power supply. In switchover mode, the LDO output can provide up to 200 mA, catering to varying power requirements with ease

FAQs
What is PM6686?
The PM6686 is a high-efficiency, current-mode synchronous step-down converter designed by STMicroelectronics. It is specifically tailored for automotive applications and is well-suited for use in advanced driver-assistance systems (ADAS), infotainment systems, and other automotive electronics requiring efficient power management.
How Does PM6686 Work?
The PM6686 operates as a current-mode synchronous step-down converter, efficiently reducing input voltage to a lower regulated output voltage. It utilizes a high-side and low-side MOSFET configuration to minimize power dissipation, while the current-mode control scheme provides fast transient response and cycle-by-cycle current limiting.
How Many Pins does PM6686 have and What are the Functions of the Pinout Configuration?
The PM6686 is housed in a 24-pin HTSSOP (PowerPAD) package. The pinout configuration includes:
- VIN: Input voltage pin.
- GND: Ground pin.
- SW: Switching node for the high-side and low-side MOSFETs.
- FB: Feedback pin for output voltage regulation.
- EN: Enable pin for turning the converter on/off.
- SS/TR: Soft-start/tracking pin for controlling start-up behavior.
- PGOOD: Power Good indicator output pin.
- VOUT: Output voltage pin.
What are the Pros and Cons of PM6686?
Pros:
- Automotive Grade: Specifically designed and qualified for automotive applications, ensuring reliability and performance in automotive environments.
- High Efficiency: Provides high-efficiency power conversion, reducing energy loss and heat generation in automotive systems.
- Wide Input Voltage Range: Allows operation with a wide range of input voltages, suitable for automotive power supplies.
- Robust Protection Features: Includes overcurrent, overvoltage, and thermal protection for enhanced system reliability.
Cons:
- Complexity: Synchronous converters can be more complex to design and optimize compared to non-synchronous alternatives.
- External Components: May require additional external components such as inductors and capacitors for proper operation.
Are There Any Equivalents/Alternatives to PM6686 for Recommendation?
Alternatives to the PM6686 from STMicroelectronics include the TPS54332 from Texas Instruments and the LT8614 from Analog Devices.
