UCC25800AQDGNRQ1

TEXAS INSTRUMENTS · Global Sourcing Parts · HVSSOP-8

UCC25800AQDGNRQ1 from TEXAS INSTRUMENTS, in a HVSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SYNC input External clock input for frequency synchronization, with the internal MOSFETs switching on the rising edge of SYNC at half the SYNC frequency and an input range of 0 V to VREG.
2 DIS/FLT bidirectional Disable input (active low) and fault code output; pulling it low inhibits switching, and it is pulled low by a 750-µA source during faults through a 100-kΩ internal pullup from VREG.
3 VREG power_out Internal regulated reference output that must be decoupled with a capacitor of 0.1 µF to 1 µF to GND, with external load kept below 1 mA.
4 OC/DT input Voltage on this pin sets the maximum dead time between the internal switching devices, with the Thevenin resistance measured at start-up to set the OCP level (2.5 kΩ to 22.7 kΩ recommended).
5 RT passive Switching frequency setting pin, where a resistor from RT to GND sets the frequency (10 kΩ minimum), and leaving it open selects the default 1.2-MHz switching frequency.
6 GND power_in Return for all control and power signals, and the layout should separate power and control signals.
7 SW output Switch node of the integrated half-bridge, which connects directly to the transformer.
8 VCC power_in Input for power and control of the device, specified from 9 V to 34 V, and it requires a high-frequency bypass capacitor between VCC and GND.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts copper • Short SYNC pin to GND when external synchronization is not used. • Minimize the current loop with high di/dt and minimize the copper area of the switch-node with high dv/dt. 35

CAD (KiCad official)

  • Symbol: UCC25800AQDGNRQ1
  • Footprint: Package_SO:HVSSOP-8-1EP_3x3mm_P0.65mm_EP1.57x1.89mm
  • 3D model: HVSSOP-8 (KiCad packages3D, STEP)
  • 3D model files: ucc25800aqdgnrq1-etched.step / ucc25800aqdgnrq1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ucc25800aqdgnrq1.step / ucc25800aqdgnrq1.glb are the bare package body.

Provenance
