Device Overview
ACT4533BYH-T is a Qorvo Buck CC/CV regulator in a SOP-8 package. For substitution or design review, the strongest comparison points are Device Function (Buck CC/CV regulator), Input Voltage (10 to 40 V), Output Current (3.5 A).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Device Function | Buck CC/CV regulator | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
| Input Voltage | 10 to 40 V | Defines compatibility with the available system input rail and its operating range. |
| Output Current | 3.5 A | Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits. |
| Exact Package | SOP-8EP, 5.0 x 6.0 mm | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
| Output Voltage | up to 12 V | Defines the output/reference voltage range or setpoint that must match the target rail, battery or threshold. |
| Switching Frequency | 125 kHz | Defines the buck-converter switching rate and affects passive-component sizing, ripple, efficiency and EMI. |
| Operating Temperature | -40 to 150 degC | Defines the qualified measurement or environmental range that the design must remain within. |
| Lifecycle / Procurement | Production | Supports current sourcing and new-design consideration. |
Power-Management Selection Notes
Buck CC/CV regulator is the stated device function value. Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. The input voltage is 10 to 40 V; this defines compatibility with the available system input rail and its operating range. Output Voltage is up to 12 V. Defines the output/reference voltage range or setpoint that must match the target rail, battery or threshold. Output Current is 3.5 A. Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits.
At 125 kHz, the switching frequency defines the operating frequency or RF band that must cover the intended signal frequencies.
The operating temperature is -40 to 150 degC; this defines the qualified measurement or environmental range that the design must remain within.
SOP-8 is the stated exact package value. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
