NOTES:
3. This is the VDD current consumed when the device is active but not switching. Does not include gate drive current.
4. Limits established by characterization and are not production tested.
5. SEE tests performed with VREF bypass capacitor of 0.22F and FSW = 200kHz. SEB/L tests done on a standalone open loop
configuration. SET tests done in a closed loop configuration. For SEL no hard latch requiring manual intervention were
observed. For more information see SEE test Report xxxx.
Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to Block Diagram and
Typical Application schematic on page 3 and page 4. VDD = 13.2V, RT = 10kΩ, CT = 3.3nF,
TA = -55 to +125°C. Typical values are at TA = +25°C.
