Efficient DC/DC Converters For Industry And Household Appliances


Torex has launched new synchronous step-down DC/DC converters ideal for industrial equipment, large household appliances, and low power consumption systems.

The newly launched XC9263/XC9264 series of DC/DC converters feature 18V operation, an internal driver transistor, and an output current of 500mA.

Other key features include an input voltage range of 3.0V to 18.0V and an output voltage range of 1.0V to 15.0V (accuracy±1.5%). The switching frequency can be selected from 500kHz, 1.2MHz, 2.2MHz to match the application.


Operation mode can be selected as PWM control (XC9263) or PWM/PFM auto switching control (XC9264). The products also offer high efficiency and low ripple voltage across a full range of loads, according to the announcement.

The soft start function is set internally at 1.0ms (TYP.). This can also be adjusted by using an external resistor and capacitor.

Internal protective functions include over-current limiting, auto reset (XC9263B/XC9264B), integration latch (XC9263A/XC9264A), and thermal shutdown. In addition, the Power Good function indicates the output voltage status.

Designers can opt for the SOT-25 package or a small USP-6C package (1.8 x 2.0 x h0.6mm).
