7LDO
Linear regulator output. It can provide up to 100 mA peak current. The LDO
regulates at 5 V If LDOREFIN is connected to GND. When the LDO is set at
5 V and LDO_SW is within 5 V switchover threshold, the internal regulator
shuts down and the LDO output pin is connected to LDO_SW through a
0.8
Ω switch. The LDO regulates at 3.3 V if LDOREFIN is connected to
VCC. When the LDO is set at 3.3 V and LDO_SW is within 3.3 V switchover
threshold, the internal regulator shuts down and the LDO output pin is
connected to LDO_SW through a 1.1
Ω switch. Bypass LDO output to GND
with a minimum of 4.7 F ceramic capacitor.

LDOREFIN
Feedback of the adjustable linear regulator. Connect LDOREFIN to GND for
fixed 5 V operation. Connect LDOREFIN to VCC for fixed 3.3 V operation.
LDOREFIN can be used to program LDO output voltage from 0.7 V to 4.5 V:
LDO output is two times the voltage of LDOREFIN. The switchover function
is disabled in adjustable mode.
9LDO_SW
Source of the switchover connection. LDO_SW is the switchover source
voltage for the LDO when LDOREFIN is connected to GND or VCC.
Connect LDO_SW to 5 V if LDOREFIN is tied to GND. Connect LDO_SW to
3.3 V if LDOREFIN is tied to VCC.
10
OUT1
Output voltage sense for the switching section 1.This pin must be directly
connected to the output voltage of the switching section. It provides also the
feedback for the switching section 1 when FB1 is tied to GND/VCC.
11
FB1
Feedback input for the switching section 1:
– If this pin is connected to GND, OUT1 operates at 5 V
– If this pin is connected to VCC, OUT1 operates at 1.5 V
– This pin is connected to a resistive voltage-divider from OUT1 to GND to
adjust the output voltage from 0.7 V to 5.5 V.
12
ILIM1
Positive current sense input for the switching section 1. It is possible to set a
threshold voltage that is compared with 1/10th of the GND-PHASE1 drop
during the off time.
13
PG1
Power Good output signal for the section 1. This pin is an open drain output
and It is pulled down when the output of the switching section 1 is out of
+/- 10% of its nominal value.
14
EN1
Enable input for the switching section 1.
– If EN1 < 0.8 V the switching section OUT1 is turned off and all faults are
cleared.
– If EN1 > 2.4 V the switching section OUT1 is turned on.
– If EN1 is connected to VREF2, the switching section OUT1 turns on after
the switching section OUT2 reaches regulation.
15
HGATE1
High-side gate driver output for section 1.
16
PHASE1
Switch node connection and return path for the high-side driver for the
section 1.It is also used as positive and negative current sense input.
17
BOOT1
Bootstrap capacitor connection for the switching section 1. It supplies the
high-side gate driver.
18
LGATE1
Low-side gate driver output for the section 1.
19
PVCC
5 V low-side gate drivers supply voltage input. Bypass to PGND with a 1
μF
capacitor.
