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.

SP9718
1.5A LOW-NOISE PWM STEP-DOWN REGULATOR
DESCRIPTION
The SP9718 is low-noise pulse-width-modulated,
DC-DC step-down converter. It powers logic and
transmitters in small wireless systems such as
cellular phones, communicating PDAs, and
handy-terminals. The device features an internal
synchronous rectifier for high efficiency; it requires
no external Schottky diode. Excellent noise
characteristics and fixed-frequency operation
provide easy post-filtering. The SP9718 is ideally
suited for Li-Ion battery applications. It is also
useful for +3V or +5V fixed input applications.
The device operates in one of four modes. Forced
PWM mode operates at a fixed frequency
regardless of the load. Shutdown mode places the
device in standby, reducing quiescent supply
current to under 0.1μA.
The SP9718 can deliver over 1.5A. The output
voltage can be adjusted from VREF to VIN. The
input range is from 2.0V to 5.0V. Other features of
the SP9718 include high efficiency, low dropout
voltage. It is available in a space-saving 8-pin SOP
package.
