SY8008 ultra-small step-down module

Overview

Ultra-small DCDC step-down module using SY8008/SY8088 chip

Size : 16x11mm

Input voltage : 2.5V~5.5V

Output voltage : 0.6V~VIN

Maximum current : 1A

The pin hole spacing is compatible with hole boards.

Output voltage setting : R1=(VOUT-0.6)*R2/0.6V

Voltage ripple : input voltage 3.9V, output voltage 1.6V

SY8008 : No-load output ripple: 10mV, 88Hz; load 600mA output ripple: 5~6mV, 1.5MHz.

SY8088 : No-load output ripple: 17mV, 162Hz; load 600mA output ripple: 7~8mV, 1.5MHz.

The following is the ripple measured by an oscilloscope. Non-professional oscilloscopes have poor accuracy and the results are for reference only.
