POWER MANAGEMENT
Notes:
(1) The output voltage will have a DC regulation level higher than the error-comparator threshold by 50% of the
ripple voltage.
(2) Using a current sense resistor, this measurement relates to PGND minus the voltage of the source on the
low-side MOSFET.
(3) clks = switching cycles.
(4) Guaranteed by design. See Shoot-Through Delay Timing Diagram below.
(5) Measured in accordance with JESD51-1, JESD51-2 and JESD51-7.
(6) This device is ESD sensitive. Use of standard ESD handling precautions is required.
