NAME TPS65050 TPS65051 TPS65052 TPS65054 TPS65056
Power supply for digital and analog circuitry of DCDC1, DCDC2
V
CC
3 3 3 3 3 I and LDOs. This pin must be connected to the same voltage supply
as VINDCDC1/2.
Input to adjust output voltage of converter 1 between 0.6 V and V
I
.
FB_DCDC1 24 24 24 24 24 I Connect external resistor divider between VOUT1, this pin, and
GND.
Select between Power Safe Mode and forced PWM Mode for
DCDC1 and DCDC2. In Power Safe Mode, PFM is used at light
MODE 32 32 32 32 32 I loads, PWM for higher loads. If PIN is set to high level, forced
PWM Mode is selected. If Pin has low level, then the device
operates in Power Safe Mode.
Input voltage for VDCDC1 and VDCDC2 step-down converter. This
VINDCDC1/2 21 21 21 21 21 I
must be connected to the same voltage supply as V
CC
.
Feedback voltage sense input, connect directly to the output of
VDCDC2 18 18 18 18 18 I
converter 2.
TPS65050 and TPS65051: Feedback pin for converter 2. Connect
DEFDCDC2 to the center of the external resistor divider.
TPS65052 and TPS65056: Select pin of converter 2 output
DEFDCDC2 17 17 17 17 17 I voltage.
High = 1.3 V, Low = 1 V
TPS65054: Select pin of converter 2 output voltage.
High = 1.05 V, Low = 1.3 V
L1 22 22 22 22 22 O Switch pin of converter 1. Connected to Inductor .
