PACKAGE PIN DESCRIPTION
PACKAGE PIN #
PIN SYMBOL
FUNCTION
16 Lead SO Narrow
1, 2, 3, 4
VID0VID3
Voltage ID DAC input pins. These pins are internally pulled
up to 5.0 V providing logic ones if left open. The DAC range
is 2.14 V to 3.54 V with 100 mV increments. VID0 VID3
select the desired DAC output voltage. Leaving all 4 DAC
input pins open results in a DAC output voltage of 1.244 V,
allowing for adjustable output voltage, using a traditional
resistor divider.
5
SS
Soft Start Pin. A capacitor from this pin to LGND in conjunc-
tion with internal 60 μA current source provides Soft Start
function for the controller. This pin disables fault detect func-
tion during Soft Start. When a fault is detected, the Soft Start
capacitor is slowly discharged by internal 2.0 μA current
source setting the time out before trying to restart the IC.
Charge/discharge current ratio of 30 sets the duty cycle for
the IC when the regulator output is shorted.
6, 12
NC
No Connection.
7
COFF
A capacitor from this pin to ground sets the time duration for
the on board one shot, which is used for the constant off time
architecture.
8
VFFB
Fast feedback connection to the PWM comparator. This pin
is connected to the regulator output. The inner feedback loop
terminates on time.
9
VCC2
Boosted power for the gate driver.
10
VGATE
MOSFET driver pin capable of 1.5 A peak switching current.
11
PGND
High current ground for the IC. The MOSFET driver is refer-
enced to this pin. Input capacitor ground and the anode of
the Schottky diode should be tied to this pin.
13
VCC1
Input power for the IC.
14
LGND
Signal ground for the IC. All control circuits are referenced to
this pin.
15
COMP
Error amplifier compensation pin. A capacitor to ground
should be provided externally to compensate the amplifier.
16
VFB
Error amplifier DC feedback input. This is the master voltage
feedback which sets the output voltage. This pin can be con-
nected directly to the output or a remote sense trace.
