What is STNRGPF02 used for?
The STNRGPF02 is designed for high-efficiency AC-DC power supplies in industrial equipment, server power units, and telecom infrastructure where interleaved power factor correction is required to meet IEC 61000-3-2 harmonics standards. Its built-in digital inrush current limiter simplifies compliance with inrush limits, making it a strong choice for 300 W to 2 kW PFC front-end stages in UPS systems and EV charging stations.

Frequently Asked Questions
How does the 2-channel interleaved PFC architecture in the STNRGPF02 reduce input filter requirements?
By operating two boost channels 180° out of phase, the STNRGPF02 interleaving reduces the input current ripple amplitude by up to 50%, allowing designers to use smaller differential-mode EMI filter inductors and capacitors. This directly cuts BOM cost and board area compared to a single-channel PFC stage at the same power level.
What logic supply voltage does the STNRGPF02 require, and how does it interface with a digital controller?
The STNRGPF02 operates from a 3 V to 5.5 V logic supply (nominal 5 V), making it compatible with 3.3 V or 5 V digital controllers and DSPs. Its current-mode PWM control interface allows a host microcontroller or DSP to set switching frequency, current reference, and enable/disable the inrush limiter via digital signals without requiring level translation.
When is the embedded digital inrush current limiter in STNRGPF02 a preferred alternative to an NTC thermistor?
Unlike NTC thermistors, the STNRGPF02's digital inrush limiter maintains consistent limiting performance regardless of ambient temperature, avoiding the warm-restart problem where a hot NTC has low resistance and allows full inrush current on a second power cycle. This is especially valuable in server power supplies and industrial UPS systems that undergo frequent hot restarts.
For a 600 W server power supply PFC stage, what switching frequency range does the STNRGPF02 support?
The STNRGPF02 supports programmable switching frequencies suitable for 600 W and higher PFC stages, with the interleaved dual-channel design effectively doubling the apparent ripple frequency seen by the output capacitor. This allows designers to select smaller output bulk capacitors while maintaining hold-up time above 20 ms, a key requirement in server power supply specifications.
