Description
TD1489-synchronous rectification step-down
Chip solution DC-DC chip TD1489 (C431045 )
TD1489 is a synchronous buck circuit with two current detections.
This module is a solution board to verify the function of the chip
Enter the DC interface. Wide input power supply voltage range 4.7V to 40V.
The output is two USB ports with independent current limit.
Output voltage: 5V.
Total output current: 5A
The different output current limit is obtained by different sampling resistors.
