JAJSJZ4B October 2020 – June 2024 TPS54J061
PRODUCTION DATA
When the TPS54J061 begins soft start, internal circuitry detects if there is a voltage already present on the output. This can be due to a leakage current path in a multi-rail system charging the output capacitors. If the pre-biased voltage is greater than the output voltage commanded by the soft-start voltage, the TPS54J061 operates in Pulse-skip mode during the rise of soft start. When the soft-start voltage reaches a point where the commanded output voltage is greater than the pre-bias voltage, normal switching occurs.
