Verified — 8681l Ic Datasheet

Provides mechanical drawings for PCB footprint design, specifying the 0.6mm terminal pitch and 2.8mm × 2.8mm overall dimensions.

The IC operates on a fixed-frequency, peak current-mode control architecture. At the beginning of each clock cycle, the high-side MOSFET turns on. It stays on until the current sense signal reaches the level set by the internal COMP voltage. Synchronous Rectification

Input paths mapping to high-side sensing resistors for monitoring total input power and direct charging current.

When repairing modern consumer electronics, procuring verified components is paramount. The 8681L IC is actively stocked by global and local sub-component distributors. If you need sourcing, you can track current warehouse availability or buy the part directly through electronic component suppliers listed on Findchips or marketplaces like Alibaba and Amazon India .

: Input power supply connected to the external AC adapter. 8681l ic datasheet

The 8681L IC stands out due to its high efficiency, compact footprint, and robust protective features. Electrical Characteristics 4.5V to 21V DC Output Voltage Range: Adjustable from 0.8V up to 15V Continuous Output Current: Up to 3A Peak Efficiency: Up to 95% Switching Frequency: Fixed 500 kHz (typical) Feedback Voltage: 0.8V ( Advanced Capabilities Integrated MOSFETs: Low

: Found frequently in Lenovo IdeaPad and Samsung (NP series) motherboards to manage battery charging and SMBus communication.

: The IC prevents the overall hardware consumption from exceeding the maximum safe current threshold of the external power brick. Key Technical Specifications & Architecture

The OZ8681LN is a specific power management IC. The Win Source catalog notes that "the supply and demand status is limited". It is "a good choice for those who are looking for an electronic component that is suitable for their needs and requirements". It stays on until the current sense signal

Introduction The is a specialized power management integrated circuit (PMIC). It serves as a highly efficient synchronous buck (step-down) DC-DC converter. Engineers widely use this IC in consumer electronics, industrial automation, and automotive sub-systems. It efficiently regulates voltage from a higher input source down to a stable, lower output voltage.

The datasheet reveals a careful engineering trade-off. With a 10 mA bias current, the 8681L achieves an Output 1-dB Compression Point (P1dB) of approximately -5 dBm.
