This calculator provides Richtek product's chip junction temperature and maximum power dissipation calculation. It is suitable for product package selection and PCB layout design.

The design tool offers a usage design guide for DC to DC step-down power supply with PWM controller (voltage mode, CCM, OP, GM comparator) especially on loop stability control circuit. Input operation conditions, the design tool will provide recommended compensation components and Bode plot for better design margin.
