PACKAGE PIN DESCRIPTION (continued)
PACKAGE PIN #
FUNCTION
PIN SYMBOL
SO28L
13
I
LIM
Sets threshold for current limit. Connect to reference through
a resistive divider. This pin’s maximum working voltage is
1.3 Vdc.
14
REF
Reference output. Decouple with 0.1
F to LGND.
15
V
CCH2
Power for GATE(H)2.
16
GATE(H)2
High side driver #2.
17
GND2
Return for #2 drivers.
18
GATE(L)2
Low side driver #2.
19
V
CCL2
Power for GATE(L)2.
20
SS
Soft Start capacitor pin. The Soft Start capacitor controls
both Soft Start time and hiccup mode frequency. The COMP
pin is clamped below Soft Start during StartUp and hiccup
mode.
21
LGND
Return for internal control circuits and IC substrate connection.
22
V
CCH1
Power for GATE(H)1. UVLO Sense for High Side Driver sup-
ply connects to this pin.
23
GATE(H)1
High side driver #1.
24
GND1
Return #1 drivers.
25
GATE(L)1
Low side driver #1.
26
V
CCL1
Power for GATE(L)1.
27
V
CCL
Power for internal control circuits. UVLO Sense for Logic
connects to this pin.
28
R
OSC
A resistor from this pin to ground sets operating frequency
and V
FB
bias current.
