NAME
I/O*1
Description
1
VCC
O
Output of the internal regulator. A ceramic capacitor of 2.2uF is
required between this pin and ground.
2
EN
I
Enable logic input. Logic high level enables the device. Logic low
level disables the device and turns it into shutdown mode.
3
FSW
I
The switching frequency is programmed by a resister between
this pin and the SW pin.
4/5/6/7
SW
PWR
The switching node pin of the converter.
8
BOOT
O
Power supply for high-side MOSTFET gate driver. A ceramic
capacitor of
0.1μF must be connected between this pin and the
SW pin.
9
VIN
I
IC power supply input.
10
SS
O
Soft-start programming pin. An external capacitor connected to
ground sets the ramp rate of the internal error amplifier’s
reference voltage during soft-start
11
DIS
O
A gate drive output for the external disconnect FET. Connect the
DISDRV pin to the gate of the external FET. Leave it floating if
not using the load disconnect function.
12
NC
-
No connection inside the device. Connect these two pins to
ground plane on the PCB for good thermal dissipation.
13
MODE
I
Operation mode selection pin for the device in light load condition.
When this pin is connected to ground, the device works in PWM
mode. When this pin is left floating, the device works in PFM
mode.
14/15/16
VOUT
PWR
Boost converter output.
17
FB
I
Voltage feedback.
18
COMP
O
Output of the internal error amplifier, the loop compensation
network should be connected between this pin and the AGND pin.
19
ILIM
I
Adjustable switch peak current limit. An external resister should
be connected between this pin and the AGND pin.
20
AGND
-
Signal ground of the IC.
0
PGND
PWR
Power ground of the IC.
1 I: input
O: output
PWR: power
