Power Integrations’ HiperPFS™-5 family of power-factor-correction (PFC) ICs is the only PFC solution utilizing gallium nitride (GaN) technology. The highly integrated devices feature a 750 V PowiGa™ switch, achieving a 0.98 power factor and 98.3% efficiency without heatsinks for up to 250 W output.
The design example, DER-977, contains two HiperPFS-5 devices working in parallel to deliver up to 500 W output in a universal-input boost PFC stage. The board maintains a power factor over 0.9 at 20% load and higher than 0.95 at 50% load.
The design example, DER-977 , contains two HiperPFS-5 devices working in parallel to deliver up to 500 W output in a universal-input boost PFC stage. The board maintains a power factor over 0.9 at 20% load and higher than 0.95 at 50% load.
HiperPFS-5 ICs also eliminate the need for bulky heatsinks at the PFC stage. This allows exceptionally low-profile designs that are especially beneficial to flatscreen TVs, as well as industrial and commercial applications. For applications that require even higher output power, HiperPFS-5 devices allow multiple PFC stages of the same design to combine their capacity by connecting in parallel.
Highly reliable, highly integrated PowiGaN devices keep efficiency high, component count low and system design simple. In addition to HiperPFS-5, PowiGaN switches are used in a broad range of switcher IC products for more than 60 types of applications.
