KINETICS Co., Ltd. is a professional analog IC design company. It was officially established on February 1, 2004 and moved into Taipei Nangang Software Park (NKSP). KINETICS products are mainly used in power management systems.

Integrating high-tech IC design talents from the United States and Taiwan, KINETICS Inc. is dedicated to the design and development of power management ICs. We also develop and design field-effect power devices such as Trench POWER MOSFET and TVS ESD protection devices to provide customers with more competitive power management system components and effectively protect the safety of electronic products.

KINETICS Technology Co., Ltd. holds several U.S. patents for synchronous rectification power management ICs. Based on these patented technologies, we continue to develop and design more forward-looking and high-performance power management ICs, and keep pace with world-class power management design companies.

QINGLI Technology uses high-density Trench POWER MOSFET process to design products, and adopts the industry's most advanced packaging and the most sophisticated packaging type, which is particularly suitable for handheld electronic product systems.

The TVS ESD protection components of QINGLI Technology are the most advanced packaging type and are adopted by many international system manufacturers. The fine packaging type is particularly suitable for electronic communication products, effectively and precisely protecting the system for safe use.

KINETICS Co., Ltd. provides closer customer service in a synchronous growth mode, allowing customers and KINETICS to achieve a win-win situation in terms of industrial technology and market competition.

In accordance with the provisions of the Recycling and Environmental Protection Act on banned substances, the company develops green products with pollution-free raw materials. The products are inspected and certified by the internationally renowned certification agency SGS and fully comply with the ROHS world environmental protection standards.

In September 2005, KINETIC TECHNOLOGY CO., LTD. passed the AFQA (ISO 9001: 2008) certification.

SP6878 Overview

Quasi-resonant PWM controller

Features

Product Name: Quasi-Resonant PWM Controller


Product model: SP6878


Product Description:


The SP6878 is a low cost, quasi-resonant flyback


controller where the maximum frequency is below


100KHz. The internal valley detector ensures the


converter operates at quasi-resonant operation over


wide range of line voltage. To reduce the standby


power loss and increase the efficiency at light load, a


proprietary burst mode design is applied. It would


provide the users a superior AC/DC power


application of higher efficiency, low external


component counts, and lower cost solution for


applications.


The SP6878 features more protections or functions


for the following characteristics: over voltage


protection (OVP); over temperature protection


(OTP); over load protection (OLP).



feature:


High-Voltage BCD Process


??Under Voltage Lockout (UVLO )


??Quasi-Resonant Control


??Internal 4ms Soft Start


??Over Temperature Latch Shutdown


??OLP (Over Load Protection)


??OVP (Over Voltage Protection) on Vcc Pin


??100KHz Maximum Frequency


??800mA Driving Capability


SP6878 is available by SOP-8/ DIP-8P packages.
