Feedback Controller With Low Operating Voltage
The IPS25 is a low-voltage current sensing feedback controller used in switch mode power supplies to control load-side current and voltage. It uses a series regulator off the VCC pin for maximum flexibility to power the chip. The IPS25 incorporates a trimmed 1.33V reference for current sensing. The voltage sensing section uses a trimmed temperature stable voltage reference of 2.6V.
Features
- Dual precision regulators for SMPS voltage and current control
- Output currents up to 0.8A
- Output voltage down to 2.6V
- Operates with grounded optocoupler
- Series regulator for VCC supply up to 30 volts
Applications
- Fast chargers for power tools and other applications
- Battery eliminators
- Industrial and bench-type power supplies
- Distributed power systems
