RS Components has announced availability of two new ranges of power semiconductors from Power Integrations. Delivering high energy efficiency with integrated protection features, the new offering from RS includes the LinkSwitch-TN2 family of offline switcher ICs and the HiperPFS-4 family of power factor correction (PFC) ICs.
The LinkSwitch-TN2 AC-DC converter devices offer excellent load and line regulation and deliver high flexibility with support for buck, boost and flyback topologies. This makes them ideal for engineers designing non-isolated offline switching power supplies for a range of markets including appliances, metering and smart LED drivers, as well as IoT and home and building automation applications.
LinkSwitch-TN2 ICs offer a selectable device current limit for design flexibility. Family protection features include auto-restart for short circuit and open loop faults, which limits power delivery to 3% of maximum, in addition to output over-voltage protection (OVP), input over-voltage protection and over-temperature protection (OTP).
The HiperPFS-4 family of PFC controller chips is optimised for a high power factor and high efficiency across various load ranges. Eliminating the need for external current-sense resistors and their associated power loss, the family offers high levels of integration and includes a 600 V rated MOSFET to deliver a very small PFC stage form factor.
Targeting a wide selection of applications including appliances, high-power adaptors and high-power LED lighting, plus consumer and computing devices, key features of the HiperPFS-4 family include greater than 95% efficiency from 10% to 100% load; less than 60 mW no-load consumption at 230 V a.c.; a power factor of greater than 0,95, achievable at 20% load; and EN61000-3-2 Class C and D compliance. Protection features include over-voltage, under-voltage lockout, OTP, and cycle-by-cycle current and power limits for overload protection.
