The Series STR-A6100 are PRC topology ICs (fixed off-time and variable on-time control) designed for a relatively low output power SMPS design of which output power is up to 20 W at universal input or 24 W at 230 VAC input. The auto-standby function reduces input power consumption to less than 50 mW at 230 VAC input by the burst-mode operation, which is stabilized by the auto-bias function to avoid a hiccup phenomenon. Current-mode feedback and leading-edge blanking stabilize the entire power supply operation. Various protections such as overvoltage, overcurrent, overload, thermal shutdown, and an avalanche-guaranteed MOSFET secure good system-level reliability.

These devices are provided in an 8-pin mini-DIP plastic package.
