TI UCC28063ADR

间歇（跃迁）

Overview

This part is identical to UCC28063 with the exception that the TSET pin Open/ Short Fault Detect and the CS pin Open Fault Detect features are removed. Removal of these Fault Detect features provides a higher degree of noise immunity to provide increased "ride-through" for applications where significant voltage noise could be coupled onto the TSET or CS pins during conditions of fast transient, surge or impulse noise on the AC Supply.

Expanded system level protections feature input brownout and dropout recovery, output over-voltage, open-loop, overload, soft-start, phase-fail detection, and thermal shutdown. The additional FailSafe over-voltage protection (OVP) feature protects against shorts to an intermediate voltage that, if undetected, could lead to catastrophic device failure. Advanced non-linear gain results in rapid, yet smoother response to line and load transient events. Reduced bias currents improve stand-by power efficiency. Special line-dropout handling avoids significant current disruption and minimizes audible-noise generation.
