Pin Functions

PIN I/O DESCRIPTION
NAME NO.
C1F+ 6 – Positive terminal of the flying capacitor C1F
C1F− 8 – Negative terminal of the flying capacitor C1F
C2F+ 4 – Positive terminal of the flying capacitor C2F
C2F− 3 – Negative terminal of the flying capacitor C2F
EN 1 I Device-enable Input.
− EN = High disables the device. Output and input are isolated in shutdown mode.
− EN = Low enables the device.
GND 9 – Ground
FB 10 O TPS60500: connect via voltage divider to VO
TPS60501 to TPS60503: connect directly to VO
OUT 7 O Regulated 3.3 V, 1.8 V, 1.5 V, or adjustable power output
Bypass OUT to GND with the output filter capacitor Co.
PG 2 O Open drain power good detector output. As soon as the voltage on OUT reaches about 97% of its nominal value this pin goes high.
VIN 5 I Supply Input. Connect to an input supply in the 1.8-V to 6.5-V range.
