18V step-down “micro DC/DC converters” integrate a coil
An internal coil simplifies the board layout and makes it possible to minimize radiation noise and circuit operation trouble. Delivered in a 3.0×3.0x1.7mm package, the device takes a maximum input voltage of 18V for a wide range of industrial equipment and IoT devices, including refrigerators and air conditioners.
Operating voltage range is 3V to 18V with a maximum output current of 0.5A, at a switching frequency of 1.2MHz. The XCL225 uses PWM control to provide minimum output ripple voltage by fixing the operating frequency. The XCL226 uses PWM/PFM auto switching control to lower the operating frequency at light loads which reduces power dissipation and realizes high efficiency from light loads to heavy loads. The output voltage can be set within a range of 1V to 15V using external resistors. A soft start function is set internally to 1.0ms (typ.) which can be adjusted using an external resistor.
