2. Specifications
Recommended operating conditions, TA = -40°C to +125°C, VIN = 3V to 36V, unless otherwise specified. Typical values are at TA = +25°C.
Boldface limits apply across the operating temperature range (-40°C to +125°C). (Continued)

Notes:
6. Test condition: VIN = 36V, FB forced above regulation point (0.6V), no switching, and power MOSFET gate charging current not included.
7. Established by both current sense amplifier gain test and current sense amplifier output test at IL = 0A.
8. Parameters with Min and/or Max limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by
characterization and are not production tested.
9. Minimum on-time required to maintain loop stability.
