UCC28632DR

Texas Instruments · AC-DC Controllers And Regulators · SOIC-7

UCC28632DR from Texas Instruments, in a SOIC-7. 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 VSENSE input Sense pin for transformer bias winding providing output feedback regulation, over-voltage protection (OVP) at 120% of regulation level, and input voltage sensing for under-voltage protection.
2 SD input Latching fault shutdown input pin with internal pull-up current source (185-235 µA); may be connected to external NTC temperature sensor with rising trip point at 3.5 V and falling trip point at 2.0 V.
3 CS input Current sense input from primary-side sense resistor; peak voltage ranges from 172 mV at minimum demand to 800 mV at maximum demand with 30 mV/µs slope compensation.
4 GND power_in Ground reference connection for all signals.
5 DRV output Gate drive output for external flyback MOSFET with 1-A source and 2-A sink current capability; output impedance is 22-35 Ω (high) and 1.2-2.5 Ω (low).
6 VDD power_in Bias supply input pin decoupled with 1-µF ceramic bypass capacitor; requires 13.0-16.5 V for start-up and maintains minimum operating voltage of 7.3-8.5 V after start-up with over-voltage protection at 16.5-18.3 V.
8 HV power_in High-voltage input connection for internal start-up current source; accepts up to 700 V from AC or DC supply with external 180-220 kΩ current-limiting resistor; supplies start-up current and bias power during fault conditions.
