Overview
The SC4614MSTRT is a Semtech switching controller utilizing a Buck topology with one output. It operates at a switching frequency of 500 kHz and features programmable output voltage. The device supports non-isolated configurations and includes voltage mode PWM control. It functions within an operating temperature range of -40°C to +85°C. Key electrical parameters include a rise time and fall time of 41 ns, with a quiescent supply current of 5 mA. The component lacks a shutdown function and is housed in an MSOP-10 package for surface mount installation.
Feature Summary
- Voltage mode PWM control architecture
- Programmable output voltage capability
- High-speed switching transitions
Applications
- General purpose DC-DC conversion systems
- Embedded power management circuits
- Industrial control board power supplies
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape specifications. Confirm that the MSOP-10 package variant matches the design requirements. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing procurement orders.
Selection Notes
Select this component when a dedicated switching controller is required rather than an integrated regulator. Ensure the design accommodates external power switches due to the controller-only nature. Verify that the 500 kHz frequency aligns with thermal and efficiency targets. Consider the absence of a shutdown feature if low-power standby modes are necessary for the application.
Part Context
This part belongs to the Semtech PMIC portfolio, specifically within the switching controllers category. It serves as a core power management IC designed for efficient voltage regulation. The component is distinct from integrated regulators by requiring external MOSFETs for power delivery.
Replacement Considerations
Consult Semtech official substitution lists for verified alternatives. Generic cross-references may not match the specific 41 ns timing or 5 mA quiescent current characteristics.
