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 VI. 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. VINDCDC1/2 21 21 21 21 21 I This must be connected to the same voltage supply as VCC. 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 . 7 Submit Documentation Feedback |
