SMPS Controller With Internal Error Amp and Reference
The IN-PLUG IPS315 is an enhanced low input voltage version of the IPS15. It includes additional features such as soft start. Like the IPS15, the IPS315 was designed for low-cost, high-efficiency, low-power switching power supplies. It contains a shunt-regulator, a precision oscillator, a PWM with its associated comparator, error amplifier, error reference, and loop compensation components as well as all the necessary biasing and protection circuitry (thermal shutdown, under-voltage, and over-current).
Features
- Reduced VCC for lower voltage requirements, such as automotive applications
- Low cost solution for low-power off-line flyback applications
- Simple, less critical, lower cost transformer
- 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
- Power shut-down for stand-by modes
- Cycle-to-cycle over-current protection
- Under-voltage protection
- Error amp and voltage reference for non-isolated and DC-DC 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
