Device Overview
ACT4525YH-T is a Qorvo CC/CV step-down DC/DC converter with USB auto-detect in a SOP-8EP package. Selection of this exact part is driven primarily by Device Function (CC/CV step-down DC/DC converter with USB auto-detect), Input Voltage (4.5 to 36 V), Output Current (up to 3.5 A).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Device Function | CC/CV step-down DC/DC converter with USB auto-detect (Official Qorvo product page) | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
| Input Voltage | 4.5 to 36 V (Product page) | Defines compatibility with the available system input rail and its operating range. |
| Output Current | up to 3.5 A (Product page) | Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits. |
| Exact Package | SOP-8EP | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
| Switching Frequency | 125 kHz (Product page) | Defines the DC/DC converter switching rate and therefore affects magnetics, ripple, switching loss and EMI behavior. |
| Lifecycle / Procurement | Discontinued | Affects procurement continuity and the risk of selecting the part for a new design. |
Power-Management Selection Notes
At CC/CV step-down DC/DC converter with USB auto-detect, the device function defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. Technical condition: Official Qorvo product page. The input voltage is 4.5 to 36 V; this defines compatibility with the available system input rail and its operating range. Technical condition: Product page. For output current, up to 3.5 A is the approved value. Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits. Technical condition: Product page.
The switching frequency is 125 kHz; this defines the operating frequency or RF band that must cover the intended signal frequencies. Technical condition: Product page.
For exact package, SOP-8EP is the approved value. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
For lifecycle / procurement, Discontinued is the approved value. Affects procurement continuity and the risk of selecting the part for a new design.
