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

In recent years, due to improvements in ADAS (Advanced Driving Support System) and autonomous driving, the number of on-board cameras corresponding to sensing and viewing applications is increasing in a car. The need to reduce current consumption and space saving in the camera module also follows. The XD9263 / XD9264 series developed this time are 18V operation, 500mA output current, synchronous rectification step-down DC/DC converter with built-in driver Tr, which can meet the above-mentioned market requirements and is the most suitable power supply IC 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 to 15.0V (accuracy ±1.5%), and the operating frequency is 2.2MHz.
The control mode can be selected from PWM control (XD9263) and PWM/PFM automatic switching control (XD9264). High efficiency and low ripple voltage are achieved in the entire load range from light load to heavy load.
The soft start function has been internally set to 1.0ms (TYP.), and it can also be adjusted arbitrarily through external resistors and capacitors. Protection features include over current limit, automatic 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 soft-start function can be combined to control the output voltage sequence. The lead package SOT-25 and the small package USP-6C (1.8 x 2.0 x h0.6 mm) can be selected according to the application. This product meets the automotive IC quality standard AEC-Q100 Level 2 (105°C), and PPAP documents can be provided according to customer requirements. You can rest assured that this product can be used in automotive applications.
