applications.
Advanced
AEC-Q100 Qualified With the Following Results:
features such as reduced dead-time drive and auto
Device Temperature Grade 1: –40°C to 125°C
zero crossing are used to optimize efficiency over the
entire load range.
Device Human Body Model ESD Classification
Level H2
The SKIP pin provides immediate CCM operation to
support controlled management of the output voltage.
Device Charged Device Model ESD
In addition, the TPS51604-Q1 supports two low-
Classification Level C3B
power modes. With the PWM input in 3-state,
Reduced Dead-Time Drive Circuit for Optimized
quiescent current is reduced to 130 µA, with
