Product details

Flyback controller with integrated 800 V MOSFET — PG-DIP-7

The Infineon ICE5AR0680BZSXKLA1 is an offline flyback switching regulator from the CoolMOS™ CoolSET™ family, integrating a PWM controller and an 800 V MOSFET in a through-hole PG-DIP-7 package. It delivers up to 39 W of isolated output power at a fixed 100 kHz switching frequency, with a 75% maximum duty cycle.

Wide junction temperature range — industrial and outdoor environments

The 39 W output is typically achieved with a forced-air or convection-cooled heatsink.

Control features: enable, soft start, and synchronization

The ICE5AR0680BZSXKLA1 includes an enable pin for sequenced startup, a soft-start function that limits inrush current during power-up, and a synchronization input that allows the switching frequency to be locked to an external clock. In multi-converter systems — for example, a flyback supplying the control board and a second converter for the IGBT gate drive — the sync pin prevents beat-frequency noise that would otherwise couple through the shared input rail. The soft start also reduces stress on the output rectifier and bulk capacitor during the first few switching cycles.

Frequently asked questions

Where can I buy ICE5AR0680BZSXKLA1?

The ICE5AR0680BZSXKLA1 is sourced through independent distribution and can be ordered against an RFQ. Submit a request for current pricing and availability — a quote will be returned with traceable stock and a firm price for your quantity.

What is the replacement for ICE5AR0680BZSXKLA1?

There is no official replacement announced because the part is still active. For a higher-power functional alternative in the same CoolSET family, the ICE3AR1080VJZXKLA1 (71 W, 800 V) or ICE3BR0665JXKLA1 (74 W, 650 V) can be considered, but these are not pin-compatible drop-ins — the pinout and auxiliary winding bias differ.

Can ICE5AR0680BZSXKLA1 be used in a 24 V input flyback?

Yes, the 10 V to 25.5 V Vcc supply range covers a 24 V input rail, and the 800 V breakdown provides ample margin for the reflected voltage. The 39 W output capability is sufficient for many auxiliary supply applications at 24 V input.

What is the difference between ICE5AR0680BZSXKLA1 and ICE5AR2280BZSXKLA1?

The ICE5AR2280BZSXKLA1 is a higher-power variant in the same CoolSET family, typically rated for higher output power and with a different MOSFET on-resistance. The ICE5AR0680BZSXKLA1 is the 39 W, 800 V version; the ICE5AR2280BZSXKLA1 is designed for applications requiring more than 39 W. Both share the same PG-DIP-7 footprint and pinout, but the transformer design and heatsinking must be adjusted for the higher power level.
