Device Overview
TPS54302DDCT is the 250-piece DDC carrier option of TI’s 3 A synchronous buck converter. Integrated power MOSFETs, loop compensation and soft start reduce external circuitry, while spread-spectrum operation is intended to improve EMI behavior.

Engineering Selection Guidance
TPS54302DDCT combines the power MOSFETs and loop compensation, reducing external design complexity. Inductor, output capacitor and thermal selection still depend on VIN, VOUT and load profile; spread-spectrum operation helps EMI but does not replace layout and input-filter verification.
Procurement Notes
Texas Instruments lists the exact orderable TPS54302DDCT as ACTIVE. The verified manufacturer package is SOT-23-THIN-6 (DDC). Confirm commercial availability, lot/date-code requirements and final terms through the RFQ process.
Lifecycle status does not state HKEQGOO stock, MOQ, lead time or final availability.
Alternative Parts
LCSC lists these as alternative candidates for engineering evaluation only; interchangeability is not established. Verify electrical specifications, pinout, package, qualification and lifecycle before substitution.
