Applications
Product Details
Description
The HiperPFS™-5 family of advanced power factor correction ICs leverages the low switching losses of the 750 V PowiGaN™ switch to optimize efficiency. The high integration level and novel control algorithm minimize system footprint by reducing overall component count and inductor size. Packaged in the low profile, surface mount InSOP-T28F, the device dissipates heat directly to the PCB substrate, eliminating the need for bulky heat sinks. Robust HiperPFS-5 devices operate from low-line to 305 VAC with over 80% de-rating.
Product Highlights
Highly Integrated, Compact Footprint
- Up to 240 W peak output power for universal applications without heat sink
- Integrated 750 V PowiGaN with lossless current sensing
- Maintains high power factor up to 305 VAC and can operate continuously at up to 460 VAC during line swells
- Quasi-resonant DCM control ensures low switching losses, smaller inductor size than conventional CrM PFC, and permits use of low cost boost diode
- Integrated automatic X capacitor discharge and high-voltage start-up for self-bias
- Source potential cooling pad in InSOP package enables effective PCB cooling and minimizes EMI
High Efficiency and Power Factor across Load Range
- Up to 98.3% efficiency from 10% load to 100% load
- <40 mW no-load consumption at 230 VAC
- PF up to 0.96 achievable at 20% load
- Programmable Power Good (PG) signal for active inrush control
- User selectable power limit enables rapid prototyping: test different size HiperPFS-5 IC’s in the same design for rapid optimization
- Digital line peak detection for robust performance even with distorted input voltage from UPS or generators
- Digital power factor enhancer compensates for EMI filter and bridge rectifier distortion
- Enables paralleling of PFC stages to increase output power
- Safety certified to IEC62368
