Product overview
Description
The STPM802 is a synchronous 4-Switch single phase non inverting buck-boost DC/DC controller that regulates output voltage, from an input voltage above, below, or equal to the output voltage. It offers an adjustable fixed frequency operation and spread spectrum to reduce EMI emissions.
The IC provides inductor and output current monitor, OV/UV protections and Power Good flag. Fault protection is also provided to detect output short-circuit condition, during which the IC retries, latches off, or keeps running.
The IC implements a low power mode function in which control loop management changes in order to reduce power dissipation.
STPM802 offers a set of features to support applications that need to fulfill functional safety requirements as defined by Automotive Safety Integrity Level (ASIL) A-B-C-D depending on application TSR.
