PACKAGE PIN DESCRIPTION
PACKAGE PIN #
PIN SYMBOL
FUNCTION
28 Lead SO Wide
1
COMP
Output of the error amplifier and input for the PWM
comparators.
2
VFB
Voltage Feedback Pin. To use Adaptive Voltage Positioning
(AVP) select an offset voltage at light load and connect a
resistor between VFB and VOUT. The input current of the VFB
pin and the resistor value determine output voltage offset for
zero output current. Short VFB to VOUT for no AVP.
3
VDRP
Current sense output for AVP. The offset of this pin above the
DAC voltage is proportional to the output current. Connect a
resistor from this pin to VFB to set amount AVP or leave this
pin open for no AVP.
45
CS1CS2
Current sense inputs. Connect current sense network for the
corresponding phase to each input.
6
CSREF
Reference for current sense amplifiers and input for Power
Good comparators. To balance input offset voltages between
the inverting and noninverting inputs of the current sense
amplifiers, connect a resistor between CSREF and the output
voltage. The value should be 2/5 of the value of the resistors
connected to the CSx pins.
7
PWRGD
PowerGood Output. Open collector output goes low when
the CSREF is out of regulation.
812
VID4VID0
Voltage ID DAC inputs. These pins are internally pulled up to
3.3 V if left open.
13
ILIM
Sets threshold for current limit. Connect to reference through
a resistive divider.
14
REF
Reference output. Decouple with 0.1 μF to LGND
15
VCCH2
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
VCCL2
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 start up and hiccup mode.
21
LGND
Return for internal control circuits and IC substrate connection.
22
VCCH1
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 for #1 drivers.
25
GATE(L)1
Low side driver #1.
26
VCCL1
Power for GATE(L)1.
27
VCCL
Power for internal control circuits. UVLO Sense for Logic
connects to this pin.
28
ROSC
A resistor from this pin to ground sets operating frequency
and VFB bias current.
