STPM802-TR

OR Controllers, Ideal Diodes Overview

The STPM802-TR is a synchronous 4-switch single-phase non-inverting buck-boost DC/DC controller manufactured by STMicroelectronics. It regulates output voltage from an input voltage above, below, or equal to the output. The device integrates high-side and low-side drivers for external N-channel MOSFETs. It supports continuous conduction mode (CCM) and discontinuous conduction mode (DCM). The component operates with fixed frequency PWM control. It includes protection features such as overcurrent protection and thermal shutdown.

OR Controllers, Ideal Diodes Procurement Notes

Verify the specific datasheet version and ordering suffixes when sourcing. Confirm that the TR suffix indicates tape and reel packaging suitable for automated assembly. Ensure compatibility with the intended PCB footprint and thermal management requirements. Cross-reference part numbers with official STMicroelectronics distributors to avoid counterfeit components. Check for any recent product change notifications affecting pinout or electrical characteristics.

OR Controllers, Ideal Diodes Selection Notes

Select this controller for applications requiring a single-stage solution for both step-up and step-down conversion. Consider the external MOSFET selection based on current ratings and switching speeds. Evaluate the required input voltage range against the controller's operational limits. Assess the need for external compensation components to stabilize the feedback loop. Review the thermal performance in the target enclosure environment.

OR Controllers, Ideal Diodes Part Context

The STPM802 belongs to a family of synchronous buck-boost controllers designed for robust power management. It is distinct from standard buck or boost-only regulators due to its ability to handle input voltages crossing the output voltage level. The TR variant specifically denotes the reel packaging format. This component addresses the need for compact, high-efficiency power stages in space-constrained designs.
