High-Speed Response Non-Isolated POL DC-DC Converter
4A/9.5A BSV-M Series
8-5 P-Good pin
Output state of the converter may be obtained by using P-Good pin. This pin is pulled up internally to
+Vin pin with 47kΩ resistor. When output voltage goes out of the converter’s pre-set range, P-Good pin
becomes low.

Vout < 1.2V : | Output voltage-Set voltage | ≦ 72mV typ. -> High
Vout ≧ 1.2V : | Output voltage-Set voltage | ≦ 6.1% typ. of set voltage -> High
However, even if the above conditions are fulfilled, output voltage may decrease to Low under the
following circumstances.
・ Potential difference between input and output: Vin - Vout < 0.7
・ Input voltage less than 3V
・ Output current in over current state
・ IC’s junction temp exceeding 150ºC typ.
