SLVSD91C December 2015 – April 2024 TPS562201 , TPS562208
PRODUCTION DATA
The TPS562201 and TPS562208 have an internal 1.0-ms soft start. 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 pre-biased at start-up, the devices initiate switching and start ramping up only after the internal reference voltage becomes greater than the feedback voltage, VFB. This scheme ensures that the converters ramp up smoothly into regulation point.
