What are the key features of UC2866NG4?

  • Resonant voltage-mode control supporting dual full/half-bridge topologies for high-efficiency soft-switching power supplies
  • 500mA gate drive capability at up to 550kHz switching frequency for fast, high-power resonant converter designs
  • Wide 11.5V to 20V input range in a through-hole 16-pin PDIP package for easy prototyping and repair

What is UC2866NG4 used for?

The UC2866NG4 is designed for resonant switching power supply topologies including LLC and series-resonant converters used in server power supplies, telecom power systems, and high-efficiency DC-DC converters. Its dual full/half-bridge drive capability and resonant control technique enable zero-voltage switching (ZVS) operation, reducing switching losses and EMI in high-power industrial and communications equipment.

Frequently Asked Questions

What control topology does the UC2866NG4 support?

The UC2866NG4 is a voltage-mode resonant PWM controller that supports dual full-bridge and half-bridge converter topologies. Resonant control enables zero-voltage switching (ZVS), which significantly reduces switching losses, EMI, and thermal stress in high-frequency power conversion applications up to 550kHz.

What are the gate drive and input voltage specifications of the UC2866NG4?

The UC2866NG4 provides 500mA peak gate drive current and operates at switching frequencies up to 550kHz. Its input voltage range is 11.5V to 20V with a nominal of 12V. These specifications make it well-suited for driving MOSFETs in medium to high power resonant converters requiring fast gate charging.

What package does the UC2866NG4 come in and is it RoHS compliant?

The UC2866NG4 is housed in a 16-pin PDIP (Plastic Dual In-Line Package, JESD-30 code R-PDIP-T16), a through-hole package that is convenient for prototyping and repair. Note that the JESD-609 code e4 and Pbfree Code No indicate this part contains lead and is not RoHS compliant, so it must be processed with appropriate solder alloys.

What types of power supply systems is the UC2866NG4 best suited for?

The UC2866NG4 is best suited for resonant converter designs such as LLC resonant, series-resonant, and parallel-resonant power supplies. These are commonly found in server and telecom power supplies, industrial DC-DC converters, and high-efficiency battery chargers where soft-switching reduces losses and allows higher switching frequencies without excessive heat generation.
