What are the key features of UC3578NG4?

  • Wide 11V to 72V input voltage range covers a broad spectrum of AC-DC and DC-DC power supply topologies
  • Voltage-mode PWM control simplifies compensation design and provides predictable closed-loop behavior
  • 16-pin PDIP package enables rapid prototyping on breadboards and through-hole PCB assembly
  • Lead-free RoHS-compliant (JESD-609 e4) construction for global regulatory compliance

What is UC3578NG4 used for?

The UC3578NG4 is well suited for industrial power supplies, telecom rectifiers, and off-line converters operating from high-voltage DC buses between 11V and 72V. It is also used in bench-top prototyping and educational platforms where the through-hole PDIP package allows quick circuit assembly and testing of voltage-mode PWM control loops.

Frequently Asked Questions

Which designs are a good fit for UC3578NG4 with 11 V to 72 V?

UC3578NG4 fits industrial, embedded, and repair-oriented electronic assemblies when the design needs 11 V to 72 V and 72 V. It is a practical choice when the BOM also matches the 16-pin PDIP footprint.

How should engineers check package compatibility for UC3578NG4?

Compare the PCB land pattern, height allowance, and assembly process against the 16-pin PDIP style. The 16 pins detail is the first check before approving a replacement.

What matters when sourcing UC3578NG4 as a replacement?

Confirm the same 11 V to 72 V, 72 V, manufacturer traceability, and lifecycle status before substituting it. Buyers should also verify stock for the exact 16-pin PDIP configuration.
