Product Description

5.5V 1.5A Hi-SAT COT Step-Down Micro DC/DC

The XDL601 is an ultra-small high speed transient response PWM 1.5A synchronous step-down Micro DC/DC. Extremely fast load transient performance is as a result of a new Hi-SAT COT control method, which, when compared to standard COT control, provides less fluctuation in oscillation frequency against load and input voltage.

The XDL601 total solution size is only 30mm2 and is optimised for space constrained applications such as sensors, cameras, small control modules, telematics, infotainment & HMI.

The input voltage range is 2.5V to 5.5V and the output voltage range is 0.8V to 3.3V (accuracy ±2.0%). The switching frequency is 3MHz and the operating ambient temperature range is -40°C ~ 105°C. Thermal shutdown, integral soft-start and a built-in UVLO function are also included.

The XDL601 is available in a small DFN3625-11B (3.6 x 2.5 x 1.6mm) package which has wettable flanks.
