Torex- Smallest step-down micro DC-DC converters feature 1A output and integrated coil

Torex Semiconductor has developed the XCL219/XCL220 series of micro DC-DC converters with integrated coil and control IC. The XCL219/XCL220 series devices measure just 2.5mm x 2mm x 1mm.and are the smallest in the world in the 1A continuous output current category, says the company. The space-saving devices feature high output current and high-efficiency operation. The integrated coil simplifies the board layout and helps to minimize unwanted radiation noise The operating voltage range is 2.5V to 5.5V, and the output voltage is selectable in the range 0.8 to 3.6V (accuracy ±2%) in steps of 0.05V. The switching frequency is 3.0MHz, and PWM control (XCL219) or PWM/PFM auto switching control (XCL220) can be selected for the control method. The XCL219/XCL220 series uses HiSAT-COT, which is ideal for optical cable and PC peripheral devices that require a fast transient response, and portable and digital devices that incorporate a CPU. An ambient operating temperature of up to 105C is supported, allowing the converters to be used in industrial equipment applications, says the company.
