SLUSEZ4A March 2023 – January 2024 TPS563203 , TPS563206
PRODUCTION DATA
TPS56320x have an internal typical 1.4ms soft-start time. When the EN pin becomes high, the internal soft-start function begins ramping up the reference voltage to the PWM comparator.
If the output capacitor is prebiased at start-up, the device initiates switching and start ramping up only after the internal reference voltage becomes greater than the feedback voltage VFB. This scheme makes sure that the converters ramp up smoothly into regulation point.
