1

BI

2

CCP

Place a 3.3nF capacitor between this pin and GND

3

BEN

Boost Enable (active low). To enable the TS3300, connect this to GND. To

4

BI FB

Boost Input Feedback for Anti-Crush Voltage Setting. The BI FB pin

voltage is 392mV. To set the anti-crush voltage, refer to the Applications

Information section and to Figure 4.

5

FAC

Factory use only. Do not connect to GND or VDD. Leave open.

6

SW EN

Connect to REGIN.

7

REG EN

Output Load-Switch Logic Input Control (active low).

8

REG FB

Connect to REGIN.

9

GND

Ground. Connect this pin to the analog ground plane.

10

REGOUT

Boost Regulator Load-Switch output.

11

REGIN

Boost Regulator Load-Switch input. Connect to BO for use.

12

GND

Ground. Connect this pin to the analog ground plane.

13

BO FB

Boost Output Feedback. The BO FB pin voltage is 505mV. BO FB coupled

with a voltage divider circuit sets the boost regulator output voltage. Refer

to Figure 3.

LSW

Inductor Connection.

16

GND

Ground. Connect this pin to the analog ground plane.

EP

For best electrical and thermal performance, connect exposed paddle to

GND.
