18V Input, 3A Peak Output Current Step-Down Synchronous DC/DC Converter

The XC9280 has an operating voltage range of 4.5V~18V, can support output voltages from 1.8V~7.0V (adjustable) and continuous output currents of up to 2A (3A peak). Quiescent current is 80μA and the DC/DC uses PFM/PWM automatic switching control.

Even in the compact TSOT-26 package (2.8 x 2.9 x h1.1mm), the XC9280 can maintain on-resistance values of 0.166Ω (High Side) and 0.13Ω (Low Side), a level equivalent with previous products in larger packages. The series also features a built-in soft-start function (externally adjustable) which is effective for preventing output capacity inrush and output voltage start-up delays

Switching frequency is 1.2MHz.
