Texas Instruments UCC2818AD
- Part Number:
- UCC2818AD
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3262108-UCC2818AD
- Description:
- 6kHz-220kHz CCM PFC controller with 10.5V/10V UVLO and Smaller Gate Drive Resistor, -40°C to 85°C
- ECAD Model:
-
- Datasheet:
- ucc2818a
Description
The UCC3817A and UCC3818A family of controllers are designed for active power factor corrected preregulators. These controllers achieve near unity power factor by shaping the ac input line current waveform to correspond to that of the ac input line voltage. Average current mode control maintains stable, low distortion sinusoidal line current.
Features
Controls Boost Preregulator to Near-Unity Power Factor
Limits Line Distortion
World Wide Line Operation
Over-Voltage Protection
Accurate Power Limiting
Average Current Mode Control
Improved Noise Immunity
Improved Feed-Forward Line Regulation
Leading Edge Modulation
150-μA Typical Start-Up Current
Low-Power BICMOS Operation
12-V to 17-V Operation
Frequency Range of 6 kHz to 220 kHz
Applications
Power Factor Correction (PFC) Preregulators
AC-DC Converters
Battery Chargers
Uninterruptible Power Supplies (UPS)
