PIN FUNCTIONS

Pin

Name

Function

1

IGBTIN

Logic Input Pin for IGBT Drive.

2

IGBTOUT

Output Drive for IGBT Gate. Connect this pin to the gate of the IGBT.

3

SW

Switch Pin. This is the drain of the internal power switch.

4

RDYB

Open-Drain Power-Ready Output. RDYB becomes low when the output voltage is reached.

5

FB

Feedback Pin. Its trip voltage is 298V

6

CHG

Charge Enable Pin. A low to high transition on this pin puts the part into power delivery

mode. Once the target voltage is reached, the part will stop charging the output. Toggle

this pin will start charging again. Bring this pin low will terminate the power delivery and put

the part in shutdown. This pin can be also used to program the peak current regulation. See

the description for current programming.

7

PGND

Power Ground

8

AGND

Analog ground. Tie it directly to local ground plane.

9

VIN

Input Supply Pin. Connect it to system supply voltage. Bypass VIN to GND with a 0.1uF or

greater ceramic capacitor.

10

VIGBT

2.7V LDO output. VIGBT is the supply voltage for IGBT gate driver. Bypass VIGBT with

0.1uF cap to GND.
