Overview
| Topology | Boost Converter |
| Input voltage | 90-265 V |
| Output 1 | 400 V / 0.38 A |
Description
The LT®8312 is a power factor correction (PFC) boost controller. A LT8312-based design can achieve a power factor of greater than 0.99 by actively modulating the input current, allowing compliance with most Harmonic Current Emission requirements.
The LT8312 is well suited for a wide variety of off-line applications. The input range can be scaled up or down, depending mainly on the choice of external components. Efficiencies higher than 95% can be achieved with output power levels up to 250W.
Features
- PFC Boost with Minimum Number of External Components
- VIN and VOUT Limited Only by External Components
- Active Power Factor Correction
- Low Harmonic Distortion
- Overvoltage Protection
- Energy Star Compliant (<0.5W No-Load Operation)
- 16-Lead MSOP Package
RemarksÖ
