Product overview
Description
The STPM802A is a synchronous 4-switch single-phase non-inverting buck-boost DC/DC controller that regulates the output voltage, from an input voltage above, below, or equal to the output voltage. It offers an adjustable fixed-frequency operation and spread-spectrum capability to reduce EMI emissions.
The IC provides an inductor and output current monitor, OV/UV protections and a power-good flag. Fault protection is also provided to detect output short-circuit conditions, during which the IC retries, latches off, or keeps running.
The IC implements a low-power mode function, in which control loop management is adjusted in order to reduce power dissipation.
STPM802A offers a set of features to support applications that must meet functional safety requirements as defined by the Automotive Safety Integrity Level (ASIL) A-B-C-D depending on the application TSR.
