Working Principles

UCC3957M-3 operates by continuously monitoring the input voltage (VIN) and comparing it with a user-adjustable threshold voltage. When the input voltage falls below the threshold, the device triggers an undervoltage lockout (UVLO) protection mechanism, which can be used to control the enable pin (EN) and power good indicator (PG). The output voltage (VOUT) is regulated based on the input voltage level and the desired power management requirements.
