Enhanced Off-line SMPS Controller With Hiccup and Cycle-Skipping
The IN-PLUG IPS18 is an enhanced off-line switcher version of the IPS10. It includes additional features such as soft start and over-voltage limiting. Like the IPS10, the IPS18 was designed for low-cost, high-efficiency, low-power flyback off-line switching power supplies. It contains a shunt-regulator, a precision oscillator, a PWM with its associated comparator and loop compensation components as well as all the necessary biasing and protection circuitry (thermal shutdown, under-voltage, over-voltage and over-current).
Features
- Cycle-Skipping for minimal dissipation under light-load conditions
- Low cost solution for low-power off-line flyback applications
- Wide range PWM for stable operation at any load and line voltage
- Suitable for constant-power applications
- Operates with optocoupler or bias winding for constant voltage applications
Applications
- Standby power supplies for TV, VCR and IR remotely-controlled appliances
- Cordless phones and cellphone chargers
- Power tools fast chargers with trickle and on/off
- Laptops and personal digital assistants
- Utility meters
- Replacements for bulky plug-in transformers
