18
LDO5
5V internal regulator output. LDO5 pin supplies all gate drivers, the internal
circuitry and an external load. It can provide up to 100mA peak current.
19
VIN
Device input supply voltage. A bypass filter (4
and 4.7
μ
F) between the battery
and this pin is recommended.
20
CSENSE5
Current sense input for the switching 5V section. This pin must be connected
through a resistor to the drain of the synchronous rectifier (R
DSON
sensing) or to
the source of the synchronous rectifier (R
SENSE
sensing) to set the current limit
threshold.
21
PHASE5
Switch node connection and return path for the high side driver for the 5V section.
22
HGATE5
High-side gate driver ouput for the 5V section.
23
BOOT5
Bootstrap capacitor connection for the switching 5V section. It supplies the high-
side gate driver.
24
SKIP
Pulse skipping mode control input. It is a three states pin.
If the pin is at its high level(e.g. cnnected to LDO5) the PWM mode is enabled.
If the pin is at its low level (e.g. connected to GND), the pulse skip mode is
enabled.
If the pin is at its middle level (e.g. connected to Vref) the pulse skip mode is
enabled but limiting the min frequency to 25KHz.
25
EN5
5V SMPS enable input. The 5V section is enabled appling a high logic level
(>2.4V) to this pin, while is disabled appling a low logic level (<0.8V). When the
section is disabled the High Side gate driver goes low and Low Side gate driver
goes high. If both EN3 and EN5 pins are low and SHDN pin is high the device
enters in standby mode.
26
PGOOD5
Power Good ouput signal for the 5V section. This pin is an open drain ouput.
The pin is pulled low if the output is disabled or is out of the specified window
(approximately +/- 10% of its nominal value).
27
PGOOD3
Power Good ouput signal for the 3.3V section. This pin is an open drain ouput.
The pin is pulled low if the output is disabled or is out of the specified window
(approximately +/- 10% of its nominal value).
28
LDP3SEL
Control pin for the 3.3V internal linear regulator. This pin determines three
operative modes for the LDO3.
If LDO3_SEL pin is at its low level the LDO3 is always OFF.
If LDO3_SEL pin is at its high level the LDO3 is always ON
If LDO3_SEL pin is connected to VREF and OUT3 is greater than the LDO3
bootstrap switch threshold, the LDO3 regulator shuts down and the LDO3 pin will
be directly connected to OUT3 through a 3 (max) switch.
29
OUT5
Output voltage sense for the 5V switching section.This pin must be directly
connected to the output voltage of the switching section.
30
COMP5
DC voltage error compensation pin for the 5V switching section.
31
V
CC
Device Supply Voltage pin. Connect this pin to LDO5
32
VREF
High accuracy output voltage reference (1.237V). It can deliver 50uA. Bypass to
SGND with a 100nF capacitor.
