PIN TYPE DESCRIPTION
NAME NO.
AGND 19 — Analog ground pin
BSW 7 O Gate control pin for external battery switch. This pin goes low when ENP is set high.
CN 18 — Compensation pin for inverting converter control
CP 21 — Compensation pin for boost converter control
ENN 10 I Enable pin for the negative output voltage (0 V: disabled, VIN: enabled)
ENP 8 I Enable pin for the positive output voltage (0 V: disabled, VIN: enabled)
FBN 16 I Feedback pin for the negative output voltage divider
FBP 22 I Feedback pin for the positive output voltage divider
INN 5, 6 I Inverting converter switch input
INP 1, 24 I Boost converter switch input.
NC 12, 20 — Not connected
OUTN 13, 14 O Inverting converter switch output.
PGND 2, 3 — Power ground pin
PSN 11 I Power-save mode enable for inverter stage (0 V: disabled, VIN: enabled)
PSP 9 I Power-save mode enable for boost converter stage (0 V: disabled, VIN: enabled)
VIN 4 I Control supply input
VNEG 15 I Negative output voltage sense input
VPOS 23 I Positive output voltage sense input
VREF 17 O Reference output voltage. Bypass this pin with a 220-nF capacitor to ground. Connect the lower resistor of the negative output voltage divider to this pin
