Device Overview
Qorvo ACT4088US-T is an exact-order DC-DC converter supplied in SOT23-6. Selection of this exact part is driven primarily by Input Voltage (4.5 to 28 V), Output Current (1.5 A), Exact Package (SOT23-6).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Input Voltage | 4.5 to 28 V (Product page) | Defines compatibility with the available system input rail and its operating range. |
| Output Current | 1.5 A (12 V input to 5 V output) | Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits. |
| Exact Package | SOT23-6 | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
| Device Function | DC-DC converter | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
| Switching Frequency | 1.4 MHz (Product page) | Defines the buck-converter switching rate and affects passive-component sizing, switching loss and EMI. |
| Lifecycle / Procurement | Discontinued | Affects procurement continuity and the risk of selecting the part for a new design. |
Power-Management Selection Notes
At 4.5 to 28 V, the input voltage defines compatibility with the available system input rail and its operating range. Technical condition: Product page. At 1.5 A, the output current defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits. Technical condition: 12 V input to 5 V output. DC-DC converter is the stated device function value. Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared.
At 1.4 MHz, the switching frequency sets the power-stage switching rate and influences passive-component size, ripple, efficiency and EMI. Technical condition: Product page.
Exact Package is SOT23-6. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
Qorvo lists ACT4088 as Discontinued; end of life was announced October 30, 2020, with last time buy on May 28, 2021.
