New Automotive DC/DC Converters by TOREX

500mA Synchronous Step-Down DC/DC Converters With 18V-Operation

TOREX has launched the XD9263/XC9264 series of the 500mA synchronous step-down DC/DC converters with internal 18V-operation driver transistors for in-vehicle use (compliant with AEC-Q100 Grade 2 (105°C)).

With an input voltage range of 3.0V to 18.0V, these products are compatible with voltages supplied from navigation or other ECUs. Output voltage range is 1.0V to 15.0V (accuracy of ±1.5%), and switching frequency is 2.2MHz.

Select Your Operating Mode

Operating modes can be selected from either PWM control (XD9263) or PWM/PFM automatic switching control (XD9264), to achieve high efficiency and low ripple voltage in all load ranges from light to heavy loads. Protective features are built in including overcurrent limit, auto-reset (XD9263D / XD9264D), integral latch (XD9263C / XD9264C), and thermal shutdown. Furthermore, output voltage sequence control is possible with the power-good function and the soft-start function.

The packages for these products can be selected in accordance with the application, from pin-equipped SOT-25 or compact leadless package USP-6C (1.8x2.0x0.6mm).
