JAJSFV8A June 2018 – December 2018 TPS51200A-Q1
PRODUCTION DATA.
The TPS51200A-Q1 device provides an open-drain PGOOD output that goes high when the VO output is within ±20% of the REFOUT pin. The PGOOD pin deasserts within 10 μs after the output exceeds the size of the powergood window. During initial VO startup, the PGOOD pin asserts high 2 ms (typ) after the VO pin enters power good window. Because the PGOOD pin is an open-drain output, a 100-kΩ, pullup resistor between the PGOOD pin and a stable active supply voltage rail is required.
