TABLE A: PIN CONFIGURATIONS

NOTE: the limited pin availability of the PowerSO-10 package leads to drop some functions.

ABSOLUTE MAXIMUM RATINGS

Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is

not implied.

FUNCTION

1

LLC

Line Length Compens.

(1V typ)

Logic control input: see truth table

2

OLF

Over Load Flag

Logic output (open collector). Normally in HIGH

IMPEDANCE, goes LOW when current or thermal overload

occurs

3

MI

Master Input

In stand-by mode, the voltage on MI is routed to LNBA pin.

Can be left open if bypass function is not needed

4

LNBB

Output Port

See truth tables for voltage and port selection

5, 6, 15,

GND

Ground

Circuit Ground. It is internally connected to the die frame

7, 13

N.C.

Not Connected

Supply Input 1

15V to 27V supply. It is automatically selected when

Supply Input 2

22V to 27V supply. It is automatically selected when
