Power Integrations’ latest automotive technology for battery, converter, charger and inverter applications

Battery management systems - PI's reinforced isolated flyback and non-isolated buck converter products are idea for generating internal low voltage supply rails. The extremely low no-load consumption and high efficiency reduce background discharge of the HV battery.

Climate control & Auxiliary converters - As the market leader for integrated power supply solutions, Power Integrations has developed its own automotive power supply solutions for these applications. We offer these as galvanic isolated FlyBAck controller devices and Buck converter ICs.

Main DC-DC Converters - Depending on the specific architecture either reinforced isolated or non-isolated supply rails are required to be created from the HV system voltage which makes the 1000 V input capable solutions from Power Integrations ideal.

On-Board Chargers (OBC) - Power Integrations offers low component count, isolated and non-isolated integrated flyback and buck controller ICs ideal for the internal housekeeping supplies within an OBC. With the move to 800 V vehicle architectures, these solutions can operate at input voltages above 1000 V.

Traction Inverters - Power Integrations offers automotive qualified gate drivers and power supply ICs for the traction inverter which increase efficiency while saving space and cost and meeting functional safety. Reinforced isolation, extended creepage distance packages meet latest requirements for vehicles moving to 800 V architectures.

LinkSwitch™-TN2Q

The LinkSwitch™-TN2 family of ICs for automotive power supplies provide significant reduction in component count compared to traditional discrete solutions making it highly reliable. The device family supports buck, buck-boost and flyback converter topologies. Each device incorporates a 750 V power MOSFET, oscillator, On/Off control, a high-voltage switched current source for self-biasing, frequency jittering, fast (cycle-by-cycle) current limit, hysteretic thermal shutdown, and output and overvoltage protection circuitry onto a monolithic IC.
