Resonant-mode PWM controller IC featuring alternating outputs and fixed off-time operation. Operates with 8/7V UVLO, supporting a 50% duty cycle and up to 1MHz frequency. Delivers 500mA output current with a 1.7V output voltage, suitable for push-pull topologies. Encased in a 16-SOIC package with SMD/SMT termination, it functions across a -40°C to 85°C temperature range. Maximum supply voltage is 22V, with a maximum power dissipation of 1W.
