Torex XC9505 Series 2ch DC/DC Controller Datasheet
The document describes the XC9505 series as 2-channel DC/DC controllers featuring one step-down output (Output 1) and one inverting output (Output 2). The device supports a power supply voltage range of 2.0V to 10V and offers an oscillation frequency of typically 180kHz, with custom options for 300kHz and 500kHz.
Key features include PWM or automatic PWM/PFM switching control, soft-start functionality internally set to 10msec for Output 1, and a maximum duty ratio of 100% for step-down and 80% for inverting modes. The IC is available in an MSOP-10 package.
