The SY8386RH SY8386R SY8386 EH eH Marking IC series is a high-efficiency synchronous step-down (buck) DC-DC converter Charging IC manufactured by Silergy. It integrates high-side and low-side MOSFETs to deliver fast transient response and low ripple output. This IC is commonly used in laptop and tablet mainboards for core power and battery management functions.
The EH or eH marking identifies genuine Silergy variants of SY8386R/SY8386RH in compact QFN package configurations.
