Description

This is Automotive 38 V, 500 mA synchronous step-down switching regulator with 30 μA quiescent current. This is a type of power supply circuit used to efficiently reduce the voltage from a higher level to a lower level, making it suitable for a wide range of applications, including electronic devices, power management systems, and more.

The A6985F automotive grade device is a step-down monolithic switching regulator able to
deliver up to 0.5 A DC. The output voltage adjustability ranges from 0.85 V to VIN. The 100%
duty cycle capability and the wide input voltage range meet the cold crank and load dump
specifications for automotive systems. The “Low Consumption Mode” (LCM) is designed for
applications active during car parking, so it maximizes the efficiency at light-load with controlled output voltage ripple.

Features

1. 0.5 A DC output current

2. 4 V to 38 V operating input voltage

3. Low consumption mode or low noise mode

4. 30 µA IQ at light-load (LCM VOUT = 3.3 V)

5. 8 µA IQ-SHTDWN

6. Fixed output voltage (3.3 V and 5 V) or adjustable from 0.85 V to VIN

7. Adjustable fSW (250 kHz – 2 MHz)

8. Embedded output voltage supervisor

9. Synchronization

10. Adjustable soft-start time

11. Internal current limiting

12. Overvoltage protection

Applications:

1. Designed for automotive systems

2. Battery powered applications

3. Car body applications (LCM)

4. Car audio and low noise applications (LNM)
