Torex Semiconductor Co., Ltd. (Managing Director, Chuo-ku, Tokyo, Japan: Koji Shibamiya Daiichi Tokyo Stock Exchange: 6616, hereinafter referred to as "Torex") has developed an 18V operation driver for automotive (AEC-Q100 compliant) Tr built-in, output current 500mA, synchronous rectification step-down DC/DC converter XD9263/XD9264 series.

In recent years, due to the improvement of ADAS (Advanced Driver Support System) and autonomous driving, the number of in-vehicle cameras corresponding to sensing and viewing applications is increasing in one vehicle. There is also a need for reduced current consumption and space saving in camera modules. The XD9263/XD9264 series developed this time are 18V operation, 500mA output current, synchronous rectification step-down DC/DC converters with a built-in driver Tr, which can meet the above market requirements and are the most suitable power supply ICs for automotive camera modules.

The input voltage range of this product is 3.0V～18.0V, which can correspond to the voltage provided by navigation and other ECUs. The output voltage range is 1.0V ~ 15.0V (accuracy ± 1.5%), and the working frequency is 2.2MHz.
The control method can be selected from PWM control (XD9263) and PWM/PFM automatic switching control (XD9264), which realizes high efficiency and low ripple voltage in the entire load range from light load to heavy load.
The soft start function has been internally set to 1.0ms (TYP.), and can be adjusted arbitrarily through external resistors and capacitors. Protection features include overcurrent limit, auto reset (XD9263D/XD9264D), integral latch (XD9263C/XD9264C) and thermal shutdown. The status of the output voltage can also be monitored through the Power Good function, and the output voltage sequence can be controlled in combination with the soft-start function. Lead package SOT-25 and small package USP-6C (1.8 x 2.0 x h0.6 mm) can be selected according to the application. This product complies with the automotive IC quality standard AEC-Q100 Grade 2 (105°C), and PPAP documents can be provided according to customer requirements, so you can rest assured that this product can be used in automotive applications.
