CS = PGND, VIN to FB = 0V, RSET = 10kΩ, RTC = 27.5K, RRIN = 60kΩ,TA = TJ = -40°C to +125°C, unless otherwise noted. Typical
values are at TA = TJ = +25°C. All voltages are referenced to SGND, unless otherwise noted.) (Note 1)
Note 1: Limits are 100% tested at TA = +25°C. Limits over the temperature range and relevant supply voltage range are guaranteed
by design and characterization.
