RS2030X
Lowest Cost Green-Power Off-Line PWM Controller
Description
The RS2030 is a high performance green-power offline power supply PWM controller. It features a scalable driver for driving external NPN (13003) or MOSFET transistors for line voltage switching. This proprietary architecture enables many advanced features to be integrated into a small package (TO-92), resulting in lowest total cost solution. The RS2030 automatically enters the CRM (Cycle Reset Mode) under light-load/zero-load conditions. Consuming only 0.15W in standby, the RS2030 features over-current, short circuits and under-voltage protection mechanisms. This can minimize standby power consumption and achieve green-power functions. With a very low start-up current, the RS2030 could use a large value start-up resistor
