Yutai Technology was founded on December 12, 2005 in Hsinchu, Taiwan. It is a professional analog and mixed signal IC design company. Since its establishment, it has actively invested in R&D resources and rapidly developed new products. Our product line includes touch screen control IC, power management IC (A.DC/DC conversion; B. AC/DC conversion), white light LED driver and MEMS Microphone sensor, etc., mainly used in consumer product applications, such as wireless broadband, data communication (AP router, IAD, GPON, etc.) USB 3.0 applications (Pen-Driver, SSD, hard disk, etc.), LCD TV, monitor, set-top box, surveillance (CCTV, IP-CAM, baby monitor, etc.), tablet computer, MID, PDA, DVD player, IA, Smart phone, NoteBook products, etc. The company has branches or offices in Hong Kong, Shanghai and Shenzhen, with a total area of ​​2,500 square meters, and has set up professional laboratories and invested in professional testing equipment. We have a group of highly qualified, professional and dedicated R&D and application engineers, and the application engineers are stationed in the Pearl River Delta and the Yangtze River Delta to serve customers nearby. To provide strong support in response to customer needs. We are constantly committed to improving our quality in order to provide customers with the best service and meet market demand. The company strictly follows the process to control quality in product design, production, and shipment. The company passed the ISO 9001 international quality certification in December 2007. Customers can use Yutai products with confidence and regard Yutai as a reliable partner. After eight years of development, Yutai Technology's touch IC, DC/DC Converter and MEMS Microphone products have been successful in the market, and the products have been adopted by many first-tier manufacturers. As market competition becomes increasingly fierce and the replacement time of new products becomes shorter and shorter, Yutai's products allow customers to keep up with the market, gain competitive advantages, and further become a leader in the market to create a win-win situation.

ZTP7193T
3A, 18V, 500KHz, Synchronous Step-Down DC/DC Converter
FEATURES
DESCRIPTION
The ZTP7193T is a high-frequency, synchronous,
rectified, step-down, switch-mode converter with
internal power MOSFETs. It offers a very compact
solution to achieve a 3A continuous output current over
a wide input supply range, with excellent load and line
regulation. The ZTP7193T has synchronous-mode
operation for higher efficiency over the output
current-load range.
Current-mode operation provides fast transient
response and eases loop stabilization.
Protection features include over-current protection and
thermal shutdown.
The ZTP7193T requires a minimal number of readily
available, standard external components and is available
in a space-saving TSOT23-6L package.
4.5V to 18V input voltage
Output adjustable from 0.8V to 15V
Output current up to 3A
Integrated 85mΩ/45mΩ power MOSFET switches
Shutdown current 3μA typical
Efficiency up to 95%
Fixed frequency 500KHz
Internal soft start
Over current protection and Hiccup
Over temperature protection
RoHS Compliant and 100% Lead (Pb) Free
