High-performance DC/DC controller featuring current-mode PWM operation. This integrated circuit supports boost, flyback, and push-pull topologies with a single output phase. It operates from an 8V to 40V supply, delivering up to 500mA output current at a maximum of 13.5V. The controller offers a 50% duty cycle, 500kHz switching frequency, and a fast 50ns fall time. Packaged in a 16-SOIC for surface-mount termination, it operates across a wide temperature range of -55°C to 125°C.
