Dual Quick-PWM, Step-Down Controller
with Low-Power LDO, RTC Regulator
ELECTRICAL CHARACTERISTICS
(Circuit of Figure 1, no load on LDO, RTC, OUT1, OUT2, and REF, VIN = 12V, VDD = VCC = VSECFB = 5V, VREFIN2 = 1.0V, BYP =
LDOSEL = GND, ONLDO = IN, ON1 = ON2 = VCC, TA = -40°C to +85°C, unless otherwise noted.) (Note 3)
