SWITCHING REGULATOR SECTION AGND1 40 Analog ground connection. All analog ground pins are connected internally on the chip. AGND2 17 Analog ground connection. All analog ground pins are connected internally on the chip. Input signal indicating default VDCDC1 voltage, 0 = 3 V, 1 = 3.3 V This pin can also be connected to DEFDCDC1 10 I a resistor divider between VDCDC1 and GND. If the output voltage of the DCDC1 converter is set in a range from 0.6 V to VINDCDC1 V Input signal indicating default VDCDC2 voltage, 0 = 1.8 V, 1 = 2.5 V This pin can also be connected DEFDCDC2 32 I to a resistor divider between VDCDC2 and GND. If the output voltage of the DCDC2 converter is set in a range from 0.6 V to VINDCDC2 V Input signal indicating default VDCDC3 voltage, 0 = 1.3 V, 1 = 1.55 V This pin can also be connected DEFDCDC3 1 I to a resistor divider between VDCDC3 and GND. If the output voltage of the DCDC3 converter is set in a range from 0.6 V to VINDCDC3 V DCDC1_EN 25 I VDCDC1 enable pin. A logic high enables the regulator, a logic low disables the regulator. DCDC2_EN 24 I VDCDC2 enable pin. A logic high enables the regulator, a logic low disables the regulator. DCDC3_EN 23 I VDCDC3 enable pin. A logic high enables the regulator, a logic low disables the regulator. L1 7 Switch pin of VDCDC1 converter. The VDCDC1 inductor is connected here. L2 35 Switch pin of VDCDC2 converter. The VDCDC2 inductor is connected here. L3 4 Switch pin of VDCDC3 converter. The VDCDC3 inductor is connected here. PGND1 8 Power ground for VDCDC1 converter 4 Submit Documentation Feedback Copyright © 2005–2016, Texas Instruments Incorporated Product Folder Links: TPS65020 |
