The 2V reference is accurate to ±1.5% over tempera-
ture and load, making REF useful as a precision system
reference. Bypass REF to GND with a 0.1µF or greater
ceramic capacitor. The reference sources up to 50µA
and sinks 10µA to support external loads.
Power-on reset (POR) occurs when V
approximately 2V, resetting the undervoltage, overvolt-
age, and thermal-shutdown fault latches. The POR cir-
cuit also ensures that the low-side drivers are driven
high until the SMPS controllers are activated. The V
input undervoltage-lockout (UVLO) circuitry inhibits
switching if V
An internal soft-start gradually increases the regulation
voltage during startup to reduce the input surge cur-
rents (see the Startup Waveforms in the Typical
Operating Characteristics ).
