12V PWM Controller with Hot-Swap

Startup Sequencing (DCENI, THRESH)
The DCENI input must be above V
THRESH
for the PWM
controller to start. By connecting the DCENI inputs of
multiple devices together and having different start
thresholds (V
THRESH_
), the startup of the PWM con-
trollers can be staggered to provide power sequencing.
Connect a resistive divider from REG to THRESH to
AGND to set the start thresholds of each device
between 0.6V and 2.5V. Connect THRESH to AGND to
produce a default 1.220V threshold for DCENI.
Connecting THRESH to REG disables the converter.
See Figure 1 and the Typical Operating Circuit.
